2-Arc-Transitive Graphs of Order 4p

Abstract
A graph X is said to be k-arc-transitive if the automorphism group of X, denoted Aut(X), acts transitively on the k-arcs of X. In this paper we classify 2-arc-transitive graphs of order 4p. Index terms- S-arc-transitive graphs; quotient graphs; Cayley graphs.
