Usable. This concept is clear enough to use, but has not yet been reviewed by another trusted user.

A conjugacy class of an element xx from a group (G,)(G,\cdot) is the set {gxg1,gG}\{gxg^{-1}, g\in G\}.

It can also be viewed as the orbit of xx under the action (g,x)G×Xgxg1X(g,x)\in G\times X\longmapsto gxg^{-1}\in X of GG over X:=GX:=G.
