Anne, The digraphs in sage also have isomorphism/automorphism groups implemented. The pointer William gave you is for undirected graphs, but if you go up a level you see much more generality... sage: D = digraphs.RandomDirectedGNP(10, .2) sage: E = digraphs.RandomDirectedGNP(10, .2) sage:

, GAP uses Monte Carlo algorithms, which actually means that the results are not provably correct, just very very probably so. I have not yet checked whether this has a bearing on whether Sage's proof=True option is incorrect somewhere, but it is possible. Tom wrote: Robert Miller has been hard
