Abstract

The commuting graph of a group is a graph with vertexes set of a subset of a group and two
element are adjacent if they commute. The aim of this paper is to obtain the automorphism group of the commuting
graph of a conjugacy class in the symmetric groups. The clique number, coloring number,
independent number, and diameter of these graphs are also computed.
