g.vertices() returns the vertices in a sorted order while g.vertex_iterator() does not make any claims about the order of the vertices. If you look at the code, you'll see that g.vertices() amounts to sorted(g.vertex_iterator()). --Mike -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
