For the undirected case you could try g.cycle_basis(...): see http://doc.sagemath.org/html/en/reference/graphs/sage/graphs/generic_graph.html#sage.graphs.generic_graph.GenericGraph.cycle_basis. -- You received this message because you are subscribed to the Google Groups "sage-support" group.

I seem to be confused about the language here. For instance when asking about simple cycles in the Peterson graph it gives things like [0,4,0] but the petersen graph doesn't have any cycles shorter than length 5... -- You received this message because you are subscribed to the Google Groups "sage-support" group.

Specifically I would like to figure out what to type in order to compute the number of simple cycles in the Hoffman-Singleton graph. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
