In mathematics, especially group theory, two elements π‘Ž and 𝑏 of a group are conjugate if there is an element 𝑔 in the group such that 𝑏 = 𝑔 π‘Ž 𝑔 βˆ’ 1 . This is an equivalence relation whose equivalence classes are called conjugacy classes. In other words, each conjugacy class is closed under 𝑏 = 𝑔 π‘Ž 𝑔 βˆ’ 1 for all elements 𝑔 in the group. Members of the same conjugacy class cannot be distinguished by using only the group structure, and therefore share many properties. The study of conjugacy classes of non-abelian groups is fundamental for the study of their structure.[1][2] For an abelian group, each conjugacy class is a set containing one element (singleton set). Functions that are constant for members of the same conjugacy class are called class functions. Let 𝐺 be a group. Two elements π‘Ž , 𝑏 ∈ 𝐺 are conjugate if there exists an element 𝑔 ∈ 𝐺 such that 𝑔 π‘Ž 𝑔 βˆ’ 1 = 𝑏 , in which case 𝑏 is called a conjugate of π‘Ž and π‘Ž is called a conjuga
