Suppose that $G$ is a finite group and $X=\textit{t}^{G}$   be a conjugacy class of an elements of order 3, $ \textit{t}\in G $.The A4-graph, is a simple undirected graph stand for $\textit{A}{_{4}}(G,X)$, whose vertex set X and two vertices $ \textit{x, y}\in X $ are adjacent if they are different and satisfy  $\textit{xy}^{-1} = \textit{yx}^{-1}$. In this article, the orbits under the action of $C_{G}(\textit{t})$ on X are analyzed, along with  the description of the algebraic structure of the subgroup $<\textit{t,x}>$  such that $ \textit{x} $ is a $C_{G}(\textit{t})$ -orbit representative is provided.
