Do you mean you want the matrix as a matrix over the integers rather than over the integers mod 9? If so, then you can do the following: sage: H = G.change_ring(ZZ); H [5 0 0 0 4] [4 5 0 0 0] [0 4 5 0 0] [0 0 4 5 0] [0 0 0 4 5] sage: H.base_ring() Integer Ring --Mike --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
