Ok I understand what you're saying but this is not obvious from the documentation which says : Return True if there is a natural map from S to self. Otherwise, return False. There is nothing in this sentence that says that the function is actually changing something and stopping you from

I'd just like to remind everyone: Only the release manager should close tickets. Tim Dumol has closed #7379, even though there was a sage library patch there which needed to be merged. This is causing 4.5.rc0 to fail in much worse ways than it should. If you close tickets yourself you may be

Hi Robert and William, What does closing a ticket mean? Is it the same as providing a resolution such as fixed, wontfix, duplicate? Or is closing the ticket something that comes *after* providing a resolution? If providing resolution and closing is the same, then I recently closed a ticket out

If G is a graph and A = G.am() is its adjacency matrix and B = G.complement().am() is the adjacency matrix of its complement, then A+B should be a 01- matrix. The code below shows that sage does not always share this viewpoint. Cheers Chris # ##
