The ticket only adds a new feature allowing for the natural 0-based permutations. Otherwise it does not change the current behavior. But why shouldn't the current behaviour be deprecated? I think requiring that the domain is 0..n-1 (is possible, with a check) would be much better. Martin

Hi there! Do I understand correctly, that this patch only concerns how permutations act on matrices, and that this is defined in the matrix class? If so, I think that I wouldn't expect standard permutations (i.e., permutations of 1,...,n) to work - unless of course there is a matrix class

Ack! Sorry I didn’t reply to you earlier. Needless to say it’s working for me. I wonder if you have an old version hanging around. I presume you restarted Emacs? What are the values of `sage-mode-version’ and `sage-startup-before-prompt-command’? If you customized the latter, you will

E.g., it should know domain and codomain, and it should know what category it belongs to. I think it makes sense to let a morphism know whether it is injective or surjective. However, additional information that is certainly interesting to researchers (e.g.: Was first defined by John
