Abstract.
Let X=Cay(G,S) be a 2-valent connected Cayley digraph of a regular p-group G and let G R be the right regular representation of G. It is proved that if G R is not normal in Aut(X) then X≅[2K 1 ] with n>1, Aut(X) ≅Z 2 wrZ 2n , and either G=Z 2n+1 =<a> and S={a,a 2n+1}, or G=Z 2n ×Z 2 =<a>×<b> and S={a,ab}.
