Hellooooooooooo again !!! I finally wrote this patch, available there :
http://trac.sagemath.org/sage_trac/ticket/11961 Though the two algorithms are very similar, I thought it better to split it into two different parts, so that one can understand better how each of them works without having to bear with "if algorithm == A" every second line. Two implementations are now available, two are checked before being returned, both pass all tests. We should be on the safe side, now :-D Thank you for your help !! :-) Nathann -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
