Many thanks to all :) Just to clarify: 1. If I don't equality for all V(G2) then G1,G2 are non-isomorphic multi digraphs, right? 2. If I get equality for a single vertex (0 -> 6 in the example) then then all isomorphisms map 0 to 6 (in this case G1.automorphism_group().order() == 96)? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
