# Presentation(Non-trivial)presentation of general linear and symplectic group over Z/mZ?

I know that there exists a nice presentation (generators and relations) of the general linear group over a finite field (by Steinberg, I think). Is there also a nice presentation of $GL(n,\mathbb{Z}/m\mathbb{Z})$ for an arbitrary integer $m$? And perhaps also for the symplectic group over $\mathbb{Z}/m\mathbb{Z}$?

I was surprised that $GL(n,\mathbb{Z}/m\mathbb{Z})$ is implemented want to do some calculations in GAP, so I assume that there exists these groups with a presentation but I could not find anything in the referencescomputer and my first problem was to determine these groups. One solution (my current) is of course to determine both by brute force. But already for small m,n this takes too much time.
