Hi, It seems to me that the following is a bug.
[EMAIL PROTECTED]:~$ sage ---------------------------------------------------------------------- | SAGE Version 3.0, Release Date: 2008-04-22 | | Type notebook() for the GUI, and license() for information. | ---------------------------------------------------------------------- In [1]: G=Graph() In [2]: G.add_edges([(0,1,'a')]) In [3]: H=Graph() In [4]: H.add_edges([(0,1,'b')]) In [5]: G.is_isomorphic(H) Out[5]: True In [6]: G.is_isomorphic(H,edge_labels=True) Out[6]: True That is, G and H are graphs consisting of one edge, but one is labeled 'a' and the other 'b'. So as labeled graphs they shouldn't be isomorphic.
