Conjugacy classes may be referred to by describing them, or more briefly by abbreviations such as "6A", meaning "a certain conjugacy class with elements of order 6", and "6B" would be a different conjugacy class with elements of order 6; the conjugacy class 1A is the conjugacy class of the identity which has order 1.
The number was calculated by counting the number of even and odd conjugacy classes in the edge and corner groups separately and then multiplying them, ensuring that the total parity is always even. Special care must be taken to count so-called parity-sensitive conjugacy classes, whose elements always differ when conjugated with any even element ...

All the reflections are conjugate to each other whenever n is odd, but they fall into two conjugacy classes if n is even. If we think of the isometries of a regular n-gon: for odd n there are rotations in the group between every pair of mirrors, while for even n only half of the mirrors can be reached from one by these rotations. Geometrically ...
The symmetric group S4, consisting of all 24 permutations of four elements, has five conjugacy classes. And you can compute that there are five conjugacy classes by taking the integer partition of 4. But how can you compute how many elements each conjugacy class has? PJ Geest 14:56, 1 June 2009 (UTC)
For any subgroup of , the following conditions are equivalent to being a normal subgroup of .Therefore, any one of them may be taken as the definition. The image of conjugation of by any element of is a subset of , [4] i.e., for all .
The entries in the same row are in the same conjugacy class. Every entry appears once in each column, as seen in the file below. Every entry appears once in each column, as seen in the file below. The positions of permutations with inversion sets symmetric to each other have positions in the table that are symmetric to each other.
In mathematics, a group is said to have the infinite conjugacy class property, or to be an ICC group, if the conjugacy class of every group element but the identity is infinite. [ 1 ] : 907 The von Neumann group algebra of a group is a factor if and only if the group has the infinite conjugacy class property.
