Description
G=SL(2,ZZ) identity = matrix(ZZ, [[1,0], [0,1]]) G.cayley_table(names='elements',elements=[identity, -identity])
From this ask.sagemath.org question. Essentially, matrix groups don't seem to work out too well:
sage: G.cayley_table(names='elements',elements=[identity, -identity]) * [1 0] [0 1] [-1 0] [ 0 -1] +-------------------------------- [1 0] [0 1]| [1 0] [0 1] [-1 0] [ 0 -1] [-1 0] [ 0 -1]| [-1 0] [ 0 -1] [1 0] [0 1]
