Dear colleagues,
I have a question about the Cryst and CrystCat packages in Gap.
Is it possible to classify a given (and legitimate)
AffineCrystGroupOnRight G according to standard nomenclature?
Of course, I have a 4-dimensional example (whose point group
is SymmetricGroup(4)). I would like to know where it fits into the
Brown...Zassenhaus
classification. On the other hand, since this is really just for my own
curiosity, I don't
much want to have to read that book more carefully. It is a bit daunting.
I understand my G quite well. Besides the faithful affine
representation I have
a nice presentation and a further geometric interpretation. G is the so-called
monodromy group of the pyramid over an apeirogon (infinite sided polygon).
Thanks,
Barry.
