Conjugacy class - Wikipedia

In mathematics, especially group theory, two elements a and b of a group are conjugate if there is an element g in the group such that b = g –1 ag.This is an equivalence relation whose equivalence classes are called conjugacy classes.. Members of the same ,conjugacy class, cannot be distinguished by using only the group structure, and therefore share many properties.
