On Edge-Primitive $2$-Arc-Transitive (Bi-)Cayley Graphs

Abstract

A graph is called edge-primitive if its full automorphism group acts primitively on its edge set. In this paper, we give a complete classification of all types of finite edge-primitive $2$-arc-transitive Cayley graphs and bi-Cayley graphs.
