In this paper we shall present a natural generalisation of the notion of automorphism of a graph or digraph G, namely a twofold automorphism. This is a pair (α, β) of permutations of the vertex set V(G) which acts on ordered pairs of vertices of G in the natural way. The action of (α, β) on all such ordered pairs gives a graph which is twofold isomorphic to(More)
