A characterization is given of the class of edge-transitive Cayley graphs of Frobenius groups Zrd:Zm with r an odd prime and m odd, of valency less than 2p1 with p1 the smallest prime divisor of m. It is shown that either (rd,m)=(p,p-12)or(29,7), or such a graph is a normal Cayley graph and half-transitive. This provides new construction of half-transitive graphs. © 2014 Elsevier Inc. Source
