Pseudo A4-graphs and their properties in dihedral groups

Let G be a finite group. We introduce a new graph definition, called the pseudo A4-graph, as an extension of the classical A4-graph. The pseudo A4-graph of G or PA4-graph is a simple graph ΓG whose vertices are elements of G, and two distinct vertices a and b are joined by an edge if and only if ab−1 = ba−1. This paper...
