Abstract
We call a Cayley digraph = Cay(G, S) normal for G if G R , the right regular representation of G, is a normal subgroup of the full automorphism group Aut() of . In this paper we determine the normality of Cayley digraphs of valency 2 on nonabelian groups of order 2p 2 (p odd prime). As a result, a family of nonnormal Cayley digraphs is found.
