Some Random Thoughts about the Occult Correspondences of the Platonic 
Solids and Their Symmetries

By Anders Sandberg

Very little of modern mathematics has been used in the Cabala, which 
relies mainly on simple arithmetic operations and some basic 
combinatorics (an area which it in fact partially founded). I think 
this is regrettable, since there is a plethora of interesting 
mathematical results which could be applied to occultism. In the 
following I will discuss a few interesting areas of solid geometry and 
abstract algebra. The discussion will be rather non-mathematical, and 
I will not attempt stringency, which anyway is a bit hard to apply 
when discussing occult matters.

It is helpful to have models or good renditions of the various 
polyhedra available to visualise the various properties I will discuss 
below (like [RW] or [C]), since I cannot include pictures of the often 
quite complex structures.


The Five Platonic Solids

The Platonic solids, also known as the regular polyhedrons, are the 
three-dimensional bodies whose surfaces consist of identical, regular 
polygons which meet in equal angles at the corners. There are five 
such polyhedrons, the Tetrahedron, the Octahedron, the Cube, the 
Icosahedron and the Dodecahedron. The first three have apparently been 
known since ancient times. The others was definitely known by the 
Pythagoreans, since one of them, Timaeus of Locri, invented the 
"Platonic" correspondence between them and the elements. Plato later 
publicised their results, which is the reason they bear his name. Here 
is a table with their properties (based on [C]):

		Faces	Edges	Vertices	Schäfli	Dual	Plato
						symbol	

Tetrahedron	4	6	4		{3,3}	Tetrahedron 	Fire
Octahedron	8	12	6		{3,4}	Cube		Air
Cube		6	12	8		{4,3}	Octahedron	Earth
Icosahedron	20	30	12		{3,5}	Dodecahedron	Spirit
Dodecahedron	12	30	20		{5,3}	Icosahedron	Water

[ The Schäfli symbol represents the type of polygons making up the 
faces and the number which meet at each vertex. A cube consists of 
squares (4) and three squares meet at each corner (3), thus its symbol 
is {4,3} ]

[ Two polyhedra are duals if the vertices of one correspond one-to-one 
to the centres of the faces of the other. ]


The Platonic Correspondences are Tetrahedron: Fire, Icosahedron: 
Water, Octahedron: Air, Cube: Earth and Dodecahedron: The Quinta 
Essentia. While this is pleasing from a traditional and aesthetic 
standpoint, I have not found it workable from a more mathemagickal 
standpoint. 

These solids naturally fall into three groups, based on their 
symmetries and duals. The Octahedron and Cube, which are duals of each 
other, form one group, while the Dodecahedron and Icosahedron form 
another. The Tetrahedron form a third group with only itself as a 
member since it is its own dual. Note that the five elements are 
similarly divided: the spiritual elements are duals to the material 
elements (and a similar duality holds for actives and passives), and 
the fifth is left out or its own opposite (one is reminded of the 
concept of positive and negative aethyr in [CL]). Thus, from my 
mathemagickal standpoint, Quintessence belongs more naturally to the 
Tetrahedron, the Cube and Octahedron corresponds as normal to Earth 
and Air while Fire and Water correspond to the Dodecahedron and 
Icosahedron respectively. I will now discuss the properties of the 
various polyhedrons from different perspectives.


The Tetrahedron

The Tetrahedron classically represents Fire, and each face is also the 
alchemical triangle of fire. The Golden Dawn called it the Pyramid of 
Fire, and used it as the admission badge for the path of Shin. The 
three upper triangles represents Solar Fire, Volcanic Fire and Astral 
Fire, while the bottom triangle, often hidden from view is the latent 
heat. The upper triangles are also linked to the three fire-signs 
Aries, Saggittaurius and Leo. 

Note that each face and each vertex can be put into a one-to-one 
correspondence with an element. Each element touches the others, 
showing that the superficial divisions of Fire and Water, Air and 
Earth are really unities. No element is superior to any other, and 
they all balance each other into a very stable structure (Buckminster 
Fuller designed his entire mathematics and architecture on this simple 
fact). This represents is in my view the state before the divisions 
between the elements, and thus resonant with the Quinta Essentia, from 
which the element were formed.

Its worth noting that the tetrahedron is its own dual. At the same 
time it belongs to the 4.3.2 symmetry group, the same as the 
octahedron and the cube belongs to. In a way this reflects "Keter is 
in Malkuth, and Malkuth is in Keter", the material world subtly 
reflects the spiritual world and vice versa.

The four elements are linked with six edges, which may correspond to 
the hexagrams and the planets (the Sun is as usual in the centre). 
Seeing things this way, each planet can be seen as a path between two 
elements. Some possible correspondences (this probably requires more 
thought, and I would be happy to hear other possibilities):

Moon		Water-Fire
Mercury		Air-Fire
Venus		Water-Earth
Mars 		Fire-Earth
Jupiter		Air-Water
Saturn		Earth-Air

We will see that this planetary/double-element correspondence is 
common in the other structures too, making it very interesting.


The Octahedron

The Octahedron corresponds classically to Air. It has 8 faces 
(corresponding to Hod and mental activity?), 6 vertices and 12 edges. 
The edges naturally correspond to the zodiac. They can be arranged in 
such a manner that the four triplicities border a triangular face each 
without overlap. These faces cover half the surface, leaving 4 
incomplete faces with signs from three elements along each edge (this 
may signify an absence of the left-out element. The octahedron thus 
consists of both the abundance of each element and its absence). At 
each corner two elements meet (creating the same planetary 
correspondences as in the tetrahedron, with the sun at the centre as 
usual). In this arrangement, each square "equator" corresponds to one 
quadruplicity. 

Another common use of the octahedral symmetry is used in banishing 
rituals (mainly the LBRP and the Rose-Cross Rite). The sphere 
encircled by three orthogonal circles is the natural projection of the 
octahedron onto the surface of a sphere. In most rituals the 
horizontal equator corresponds to the cherubic signs. This also 
corresponds to the six directions of the Yetziratic Sealing Rite [DK], 
see below for the discussion of the symmetric group. 

The octahedron fits air very well, since the various symmetries and 
correspondences are so clear and easily viewed. As we will see in the 
case of the cube, many of these symmetries are hidden or hard to 
discern in the case of Earth, perhaps signifying that the intellect  
allows us to see the structure of the world more easily than our 
physical senses, which are parts of the system we try to study.


The Cube 

The Cube naturally corresponds to Earth. It is stable, the basis of 
western architecture and salt crystallises into cubes. It has six 
faces, making some groups attribute it to Tiphareth. The six faces 
naturally fit the sephira, and can of course be linked to the planets 
except for the sun, which is placed in the centre. Another natural 
link is the folded out cube, which forms a cross. 

The eight corners of the cube neatly corresponds to three 
complementary dualities. When two dualities interact, the four 
elements are created. Now the four elements are dualized again, and we 
get eight corners representing the relative absence and abundance the 
each element. This is naturally dual to the faces of the octahedron. 
In the same way the six faces correspond to the six vertices of the 
octahedron (i.e. meetings between two quadruplicities). It is however 
not possible to arrange the three quadruplicities along the edges to 
enclose whole faces without overlaps. Does this signify the 
imperfections and limitations of the material world? 

Its an interesting fact that the cube isn't stable. If a model is made 
using toothpicks and peas, it can easily be shown that it tends to 
distort or collapse. It is however possible to inscribe a tetrahedron 
inside a cube so that its vertices meet four corners of the cube and 
its edges lie in the faces of the cube. This will stabilise it 
completely (spirit stabilises and orders matter). If two tetrahedrons 
are inscribed using different sets of vertices, they intersect and 
form a geometric body known as the "Stella Octangula" (which is an 
octahedron with pyramids added on its faces). This is a very neat 
representation of the complementarity between positive and negative 
forces, which seems to underlie much of the structure of the cube.

It is worth noting that the duality of the cube and octahedron fits 
the duality between Air and Earth. Both belong to the same symmetry 
family (called 4.3.2), to which all normal minerals and crystals 
belong (only the so-called quasicrystals belong to the icosahedral 
symmetry family). It is also an interesting fact that of the platonic 
polyhedrons, only the cube can fill space completely, without 
interstices or overlaps. Thus we see that despite that the only way to 
create a completely consistent universe out of one element is to use 
matter. The other elements are not able to bind together in the right 
way to form a stable world, but will either move around or form 
imperfect patterns.


The Icosahedron

This polyhedron traditionally corresponds to water, possibly because 
it rolls quite easily. Its 20 faces could correspond to the sephiroth 
and qlippoth, but I have so far not found any significant arrangement. 
While the octahedron and cube, belonging to 4.3.2 have many symmetries 
involving the four elements, trinities and dualities, the icosahedron 
and doedecahedron, belonging to 5.3.2 have links to the five elements 
and the trinities and dualities. Thus they correspond closer to the 
whole system than the more material elements, which deal with just the 
four elements. 

In nature these symmetries are rare, and are usually found in viruses 
and radiolaria. One reason for the rarity of these symmetries may be 
that they don't interconnect as well as the 4.3.2 group. In crystals, 
molecules and viruses with 5.3.2 symmetries organize according to the 
4.3.2 group instead, subjugating their own symmetries. The higher 
elements decay into the lower in order to form the world.

These symmetries are harder to discern, since traditionally we humans 
have a tendency to avoid high-order groups, especially odd symmetries 
(its worth noting that the number five is sacred to the Discordians 
since it is the smallest number of factors the human mind is unable to 
handle at once).

The 12 vertices can of course be viewed as the zodiac. In this case 
each sign is linked to five other signs along the edges which 
corresponds to the five elements, a quite interesting set of 
corresponences (this is of course reflected in the faces and edges of 
the dodecahedron in a similar way). This seems to imply a network 
between the signs, where each sign is transformed into five others by 
the actions of the five elements. I have so far not seen any uses for 
this system, but it is potentially interesting. 

One obvious way of arranging the elements in such a pattern is the 
following: choose two edges opposite to each other and assign them to 
an element. Then there are four edges along the "equator" if the two 
edges are regarded as the poles which can be assigned the same 
element. These edges are orthogonal to the first, and each pair of 
opposite edges are orthogonal to all others. In fact, if the opposite 
edges are joined with lines through the interior, a very neat 
structure of interlocking rectangles result, where each rectangle 
locks the other rectangles without touching them. Each pair of 
rectangles doesn't interlock, but together they form a synergetic 
whole. In this way each element can be assigned to its own edges in a 
proper way. It is interesting to note that the pattern inside each 
element belongs to the 4.3.2 symmetry group.

The icosahedron can be inscribed in the octahedron if its vertices are 
placed on the octahedron-edges in the golden ratio. In this case eight 
faces of the icosahedron lie in the plane of the faces of the 
octahedron, and the rest lie in the interior. As a general rule, the 
golden ratio is intimately linked to the 5.3.2 family of solids. This 
construction is symbolic of how the creativity and feeling of Water is 
needed to form the rational thought of Air. 

In my own system the icosahedron corresponds to water. It seems to tie 
together things in complex, apparently random ways and encompass them 
without necessarily elucidate their interrelationships. As one can 
see, the complexity of the icosahedron and dodecahedron "liquiefies" 
the various correspondences. The number of possible arrangement is 
much larger than for the relatively simple cubes and octahedrons. 


The Dodecahedron

This solid is classically attributed to spirit, probably because it 
was the last discovered and because of the pentagonal faces. Its 
twelve faces has naturally been attributed to the zodiac, and there 
have even been dodecahedral calendars. The symmetries discussed above 
exist in a dual form here too.

The dodecahedron can be seen as the union of five intersecting cubes, 
whose corners touch the vertices of the dodecahedron (this is a rather 
complex structure and hard to visualize). At each vertex three 
different cubes meet. Along each side of the dodecahedron an edge from 
a cube runs, creating a rather neat system of correspondences between 
the five elements and the edges like the system mentioned above for 
the icosahedron. 

Another way of placing polyhedrons in the dodecahedron is to use five 
intersecting tetrahedrons, whose corners touch the vertices. This is a 
most elegant configuration where the tetrahedrons seem to twist around 
each other. It exists in two different forms, essentially 
corresponding to clockwise and counterclockwise rotation. The space 
occupied by all five tetrahedons is a smaller icosahedron, another 
nice example of the power of duals. It could perhaps be seen as a 
"construction drawing" of Fire, where the Quinta Essentia takes on its 
various elemental properties, and combines them in an eternally 
rotating and twisting form. 

The evolution of the Quinta Essentia into the four elements may thus 
be described as follows: The original form of the Tetrahedron is 
created out of the primordial chaos by being the simplest and most 
stable form. It combines in various ways with itself, either by moving 
and mixing, forming the Dodecahedron and Fire, or by linking together 
and building the Icosahedron and primordial Water. However, while both 
polyhedrons are close to being perfect spheres, they don't fit 
together. These imperfect interactions betwen the growing numbers of 
polyhedrons force them to order themselves according to cubical 
symmetries, and Earth and Air are formed. As we will see, this fits 
with some results within group theory.

Before we shift our focus to the abstract properties of groups, its 
worth mentioning that there exist other polyhedrons of potential 
magickal interest. 


Other Polyhedra

One such set is the Kepler-Poinsot polyhedra, also known as star 
polyhedra. They are a generalisation of the platonic solids, where 
faces no longer have to be normal polygons but can be star-polygons 
(like pentagrams) instead, and they may intersect. The four star 
polyhedrons are called the small stellated dodechahedron, the great 
stellated dodechahedron, the great dodecahedron and the great 
icosahedron. They all belong to the same symetry group as the 
dodecahedron and icosahedron. These fascinating polyhedrons can be 
seen to correspond to the four elements. The small stellated 
dodecahedron has pentagrams as faces. The great dodecahedron, its 
dual, has intersecting pentagonal faces. The great stellated 
dodecahedron has also pentagram faces and its dual, the great 
icosahedron has triangular faces. 

I would say the great icosahedron corresponds to Fire (its faces are 
triangles, and it opens almost like an erupting flower). Its dual, the 
great stellated dodecahedron correspond to Water. The small stellated 
dodecahedron, with its pentagonal pyramids rising from the 
pentagrammal faces correspond to Air, and the almost asteroidlike (it 
looks a bit like a sphere with dents) great dodecahedron as Earth. 
Like I mentioned above, the {5.3.2} group seems to exist on a higher 
level (Perhaps in Briah if the {4.3.2} group exists in Yetzira), 
containing the symbolism and patterns of the other group in abstract 
form. 

Beside these polyhedrons, there are the Archimedian polyhedrons. These 
are polyhedrons where the faces can be different regular polygons (no 
intersections or star-faces allowed). There are 14 of these, with no 
known occult connotations. This is an area where much further 
discovery is possible.



The Magick of Groups

Groups are among the most useful mathematical concepts, and can be 
readily applied to magick (what cannot be applied?). A Group is a set 
with an associated binary operation * on the set, with the following 
three axioms:

1	There is an element e in the set such that e*x=x*e=x for all x.
2	The operation * is associative (a*b)*c=a*(b*c).
3	There exists an element x' for every x in the group, such that 
	x'*x=x*x'=e.

Note that these three axioms fit quite well with the three supernal 
sepiroth. However, the * operation seldom seems to have any obvious 
occult interpretation. 

The simplest group (except the unit group with just a unit element) is 
the cyclic 2-group Z2. It has two elements which correspond to the two 
sides of a duality. The next simplest is of course the cyclic 3-group 
with three elements, corresponding to a trinity.

The most important group in algebraic magick is of course the group of 
the four elements. However, there are two groups with four elements, 
the cyclic group Z4 and the Klein 4-group. The respective 
multiplication tables are:

		Z4					Klein
	e	a	b	c		e	a	b	c

e	e	a	b	c		e	a	b	c
a	a	b	c	e		a	e	c	b
b	b	c	e	a		b	c	e	a
c	c	e	a	b		c	b	a	e

I use e= Earth, a=Air, b=Water c=Fire.

To which group does the four element belong? This depends a bit on 
your perspective on the elements. If one sees them as a cyclic 
organisation, where each element is succeeded by the next, Z4 is a 
natural choice. However, if one carefully studies the Klein group, one 
sees that it consists of two parts. The material elements form a sub-
group, where the interactions between Air and Earth form only 
themselves. When the astral elements are added, the interactions 
between themselves also form the material elements (the descent  from 
the astral to the material plane). However, when they interact with 
matter, it can be elevated to the astral level. The group is also the 
cartesian product of two 2-groups, which fits in well with the 
division between actives/passives and astrals/materials. This is the 
reason I think the group fits best for the elements.

If the elements correspond to the Klein 4-group, what does the cyclic 
group correspond to? If one studies the quadruplicities in the 
litterature, one quickly find that practically all sets of four 
symbols correspond to the four elements. However, there seems to be 
one important quadruplicity which fits the cyclic group, the INRI 
formula. It denotes a linear progression, but at the same time the 
first and last step are the same. In terms of group theory and the 
Golden Dawn system, one could say that the first Yud represents the 
stable, unenlightened state. Nun, death and destruction, forces a 
change which leads to Resh, rebirth and light which becomes the second 
Yud, representing the relatively enlightened state where the process 
can begin anew ("Every day is an initiation"). 



Multiplication table:

	I1	N	R	I2

I1	I1	N	R	I2
N	N	R	I2	I1
R	R	I2	I1	N
I2	I2	I1	N	R

[I1 and I2 represents the first and second yud, respectively]

Its worth noting that the orbit of Nun (the elements x, x^2,x^3...) 
generates the whole group, it goes forward all the time. The orbit of 
the first Yud is simply itself, the unenlightened state cannot change 
without any external stimuli. Resh, the sun, has an orbit spanning 
itself and the first yud. Light in itself can only become no light or 
more light, not something else. However, the second yud has an orbit 
which moves backwards along the sequence, ending up at the first yud 
and then continuing around to itself. The enlightened are able to move 
as they want, and have no fear of light, death or being unenlightened. 

If we look at the orbits of the Klein group in the same way, we find 
that each element has an orbit consisting of itself and the unity 
element earth; a pure element can become material, but not create 
anything else. A mixture of element is necessary to create the whole 
universe.However, it is necessary only to start with two elements to 
create it; fire and water can produce earth and air (but not vice 
versa).

There are just one group of order five, the cyclic 5-group Z5 since 
the only groups of prime orders are cyclic (this follows from the very 
useful theorem of Lagrange which states that the orders of subgroups 
must divide the order of the group). It is interesting to see that the 
elements in themselves might form a non-cyclic group, but when Spirit 
is added, the result is cyclic. Fire emanates from spirit, and is then 
in turn transformed through Water, Air and Earth until it returns to 
its source. 

The orbits of the Z5 group naturally lead to the theory of lineal 
figures (pentagrams, hexagrams etc.). A cyclic group can be generated 
by an element in different ways, depending on its size. Z5 can be 
generated in essentially two ways: by going through each of its 
elements in turn (1234512345123...) or by going through every two 
elements (135241352413...). This corresponds to the pentagon and 
pentagram respectively. It can be shown that for a cyclic group of 
order n, every choice of a "step length" k which is relatively prime 
to n creates a lineal figure (other choices doesn't generate the whole 
group). For example, the cyclic group of order 7 can be generated by 
steps of length 1 (the heptagon), 2 (the "even heptagram)" and 3 (the 
"spiky heptagram"). The other choices will just create these three 
figures. For the cyclic group of order 8 there are just the octagon 
and octagram (stepsize 3 or 5), the steps of size 2,4 and 6 produces 
just two nested squares. For further correspondences of these figures, 
see the paper on lineal figures in [IR].

The most important group of order six is the permutation group of 
three elements (also known as the symmetric group of three letters), 
S3. It consists of the six possible permutations of three letters. 
These permutations are mentioned in the Sepher Yetzirah (which in fact 
is a precursor to the study of permutation groups), where the 6 
permutations of the three different letters Yud, Heh and Vau of the 
Name were used to create the directions (this is also used in the 
Yetziratic Sealing Rite). These permutations fit with the corners of 
an octahedron or the faces of a cube.

Such symmetric groups are very important, since it can be shown 
(Cayley's Theorem) that all groups are isomorphic to a group of 
permutations (which are subgroups of the symmetric groups). This means 
that if we have a group (say the group of elements), we can interpret 
each elements as an operation on a word. For example, if we look at 
the permutations of a four-letter word, the sub-group of permutations 
generated by the interchange of the first two or the last two letters 
is isomorphic to the klein group corresponding to the elements (the 
elements correspond to the identity,(12),(34) and (12)(34) in cycle-
notation). From an occult standpoint this is of course a natural 
interpretation of temura, which essentially deals with operations on 
different entities through the mediation of letter-permuations, not 
unlike how physicists study physical objects by studying the equations 
describing them. 

This introduces an interesting question in the Cabala, what other 
permutation-subgroups of the tetragrammaton have magickal 
correspondences? There are 24 elements in the group. This makes it 
possible to have subgrups of order 2,3,4,6,8 and 12. The subgrups of 
order 2,3 and 4 have already been discussed.The sub-group of order 12 
is known as the alternating group, and consists of all the even 
permutations of the tetragrammaton. Its interesting to note that 12 
permutations of the tetragrammaton are used linked to the zodiac and 
12 tribes of Israel [1], but they are unfortunately not purely the 
even permutations. 

The zodiac quite obviously corresponds to the cartesian product of a 
trinity (the alchemical elements) and the four elements (the klein 
group, which is Z2 * Z2). The result is Z3 * V = Z12, a quite neat 
cyclic group wich fits well with the cyclical nature of the zodiac. 
Various elements generate the whole group or subgroups (like the 
quadruplicities and trinities). 

However, this essay would become far too long if I elaborated on the 
interesting details of this (and more complex groups). Instead I 
encourage the reader to study and contemplate the meanings of the 
various mathematical concepts I have described, and find new 
structures. Mathematics is filled with fascinating objects, and their 
subtle interrelations and symbolism is an source of endless beauty.
