Great.
With regard to a next release I took a quick glance at the Schreier-Sims
algorithm:
http://www.maths.usyd.edu.au/u/murray/research/essay.pdf
(pages 25,30,34)
of which I thought it's less memory greedy. On page 35 there's described a
Todd-Coxeter Schreier-Sims algorithm which surpsingly
ATM there is hardcoded limit in the 'toPermutationIfCan'.

Amazing ;)
The stakes are high now.
I've tried the Men(n) function (Mennicke) from the Intro:
