I know that you can use
`random_matrix(ZZ,4,4, algorithm = 'unimodular')`
to generate matrices with determinant 1 (so in the special linear group). However, I'm actually more interested in the matrices with determinant -1.
Is there a 'Sage' way to do this? Or are there other functions/routines out there I should look at?
Thanks!
