First, create the group of all matrices with determinant 1 (in the
example, q is 9 and r is 5)
sage: G = SL(5, GF(9,'z'))
Th
Hi all,
How can I use sage to generate a random rxr matrix over F_q (q is a
prime power) with determinant 1?
Thanks!

Hi all, I'm confused why this code results in a graph plotted with the
(single) edges labeled with the weight between each pair of vertices:
M = Matrix([[0,1,-1,5],[1,0,-1/2,-1],[-1,-1/2,0,2],[5,-1,2,0]])
G = Graph(M,sparse=True)
G.plot(edge_labels=True)
Whereas this code does not and instead has

This is a question for sage-support, which I am ccing.
