Abstract
For G a group, X a subset of G and π a set of positive integers we define a graph \({\mathcal{C}_{\pi}(G,X)}\) whose vertex set is X with \({x,y \in X}\) joined by an edge provided x ≠ y and the order of xy is in π. Here we investigate \({\mathcal{C}_{\pi}(G,X)}\) when G is a finite symmetric group and X is a G-conjugacy class of elements of order p, p a prime.
