The short answer is yes, if you use GAP. The problem is that I don't know the syntax for group actions in GAP well enough to give you a beter answer quickly. If you post a specific question to GAP support, I think it would be answered immediately. > > Thaank youuuuuuuuuuuuuuuuuuuuuuuuuu !!!! > > 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 -- 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
