sage 5.3 and 5.2 on linux x86_64 G=Graph([(0, 3), (0, 4), (0, 5), (1, 4), (1, 5), (1, 6), (2, 5), (2, 6), (2, 7), (3, 6), (3, 7), (4, 7)] );G.is_cartesian_product()
ValueError: Something weird happened during the algorithm... Please report the bug and give us the graph instance that made it fail !!! If I comment the exception and compute product of the alleged factors get a graph of different order which can't be isomorphic to G. In addition .is_cartesian_product raises IndexError on 1. the empty graph 2. $K_1$ -- You received this message because you are subscribed to the Google Groups "sage-support" group.
