My guess is the loop issue. Unfortunately the actual code for is_transitive() seems to test all vertices (so not your "for example" issue) but using a Cython function called c_distances. Hopefully Nathann has a quick answer - he is the guru of graphs :) -- You received this message because you are subscribed to the Google Groups "sage-edu" group.
