Given an ,element, \(g \in G\), ,the “centralizer,” of \(g\) is the set \(C(g) = \{h \in G \mid hgh^{-1} = g\}\), which is a subgroup of \(G\). A theorem tells us that the size of each conjugacy class is the order of the ,group, divided by the order of ,the centralizer of an element, of the class.

Conjugacy class - Wikipedia

If G is a finite ,group,, then for any ,group element, a, the elements in the ,conjugacy class, of a are in one-to-one correspondence with cosets of ,the centralizer, C G (a). This can be seen by observing that any two elements b and c belonging to the same coset (and hence, b = cz for some z in ,the centralizer, C G ( a ) ) give rise to the same ,element, when conjugating a : bab −1 = cza ( cz ) −1 ...

Conjugacy class - formulasearchengine

An ,element, a of G lies in ,the center, Z(G) of G if and only if its ,conjugacy class, has only one ,element,, a itself. More generally, if C G ( a ) denotes ,the centralizer, of a in G , i.e., the subgroup consisting of all elements g such that ga = ag , then the index [ G : C G ( a )] is equal to the number of elements in the ,conjugacy class, of a (by the orbit-stabilizer theorem ).
