Full octahedral group
The full octahedral group O_{h} is the hyperoctahedral group of dimension 3. This article mainly looks at it as the symmetry group of the cube.
There are A000165(3) = 48 permutation of the cube. Half of them are its rotations, forming the subgroup O (the symmetric group S_{4}), and the other half are their inversions.
The inversion is the permutation that exchanges opposite vertices of the cube. It is not to be confused with the inversion of a permutation.
The Cayley table of O_{h} repeats the pattern of the Cayley table of S_{4}. If, as in this article, the S_{4} based notation is used, the result of a concatenation of elements of O_{h} can be derived from the corresponding concatenation of elements of S_{4}: With and being their respective inversions implies and .

As the hyperoctahedral group of dimension 3 the full octahedral group is the wreath product ,
and a natural way to identify its elements is as pairs with and .
But as it is also the direct product , one can simply identify the elements of tetrahedral subgrup T_{d} as and their inversions as .
So e.g. the identity is represented as and the inversion as .
is represented as and as .
A rotoreflection is a combination of rotation and reflection.
While a rotation leaves its axis and a reflection leaves its plane unchanged, a rotoreflection leaves only the center unchanged.

Overview[edit]
Truncated cuboctahedron[edit]
The vertices of the truncated cuboctahedron correspond to the elements of this group. Each of its faces of its dual, the disdyakis dodecahedron, is a fundamental domain.

3D diagrams  

The files below illustrate the subgroup C_{3v} or [3] that corresponds to the top matrix row. It contains the six permutations of the cube that leave the main diagonal fixed.

The rest of this article uses left action, i.e. means first , then , 
details  

 
This is left action again, so the 3×3 permutation matrices shown here are the transposes of those in the small permutohedron in the box above  which only makes a difference for and . 
Cubes corresponding to matrix columns[edit]
Each of the six cubes in the following collapsible boxes shows one of the basic permutations from the top row of the matrix in the bottom left position.
In the other seven positions are the products of applying the reflections along coordinate axes on these basic permutations.






Conjugacy classes[edit]
The full octahedral group has A000712(3) = 10 conjugacy classes.
Two permutations and are complementary to each other, if .
Complementary permutations sum up to a vector of 7s, and their inversion sets are complements,
so their inversion numbers sum up to 28. (Compare one of the number matrices above.)
The conjugacy classes below are always shown in complementary pairs (like inv2/ref1 or rot2/ref2).
The numbers over the triangles are the inversion numbers of the corresponding permutations. It can be seen that corresponding numbers add up to 28.

Subgroups[edit]
O_{h} has 98 individual subgroups, which are all shown in the list below. (A Python dictionary of them can be found here.)
They naturally divide in 33 bundles of similar subgroups, whose elements belong to the same conjugacy classes.
In this article these bundles are given naive names based on some of the colors assigned to their elements (like Dih_{4} green orange).
Each of them has a collapsible box below, containing representations of the individual subgroups.
These belong to 25 bigger bundles, which can be identified with a label in Schoenflies or Coxeter notation (like D_{2d} or [2^{+},4]).
Each of them has a vertex in the big Hasse diagram below.
Four different kinds of Coxeter notation can be distinguished, based on where they contain plus signs:
[...]^{+}  rotate 
[...]  reflect 
[...^{+},...^{+}]  cross 
[...^{+}, ...]  mixed

Different appearances of the same group[edit]
Symmetry group of the cuboid[edit]
The symmetry group of the cuboid C_{2}^{3} appears in two essentially different ways as a subgroup of O_{h}.
The one where the cuboid is the cube itself is the most intuitive one.
In the other one the cuboid is the original cube rotated by 45° around an axis. The one where it is rotated around the zaxis is shown below.
There are 4 individual subgroups (see above).

Symmetry group of the square[edit]
The symmetry group of the square appears in four essentially different ways as a subgroup of O_{h}. (C_{4v} or [4] being the most intuitive among them.)
There are 12 individual Dih_{4} subgroups (see above). Shown below are the four where the square is seen "from above", i.e. a point on the positive zaxis.
In the white box above the colored boxes of the four subgroups are the permutations of the square. Their 2×2 transformation matrices are the top left submatrices of the four 3×3 matrices in the same column. So the last nonzero entry of the 3×3 matrix determines the permutation in this column. (So each column has only two different permutations.) The pattern of these eight last entries identifies the subgroup. It is shown on the left in the little 4×2 matrix under the example solid.

Symmetry group of the triangle[edit]
The symmetry group of the triangle appears in two essentially different ways as a subgroup of O_{h}, with C_{3v} or [3] being the most intuitive among them.
There are 8 individual subgroups (see above). Shown below are the ones where the triangle is seen from a point on the negative main diagonal of the coordinate system.
