https://mathoverflow.net/questions/142205/presentation-of-the-monster-group mentions a presentation of the monster with 12 generators.

Creating a physical rotation puzzle that implements the monster group would be quite a task!

Wow, that's a lot less than I thought. I'm just noticing now there's also a (giant, terrible) 2-generator representation mentioned in the wiki. It's always cool how simple these huge structures can turn out to be.
