__contains__ is broken in general and special linear groups. For example: sage: identity_matrix(GF(2),2) in GL(2,CC) True
The base field of the matrix is characteristic 2, but it's reported as being a matrix over C. I reported this to sage-devel here: https://groups.google.com/forum/?fromgroups=#!searchin/sage-devel/laun/sage-devel/WwovHNaUldE/lt2pFK6BeJsJ It contains some discussion, including why using the boilerplate __contains__ probably won't work. I was about to submit a bug report, when I noticed the wiki telling me to email sage-support first. I already emailed sage-devel, so I hope I'm not spamming too much by also emailing here. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
