They have a 900 page reference and also all the C-code is freely available. Apart from that they have tables for a LOT of known finite groups. I think this is going to help a lot - they are referred to in Chapter 11 of The Handbook on Computational Group Theory and could speed up some of the algorithms. -- You received this message because you are subscribed to the Google Groups "sympy" group.
