Indeed, this might be another interesting collection, possibly even more interesting! That would be A000638. Is there (some sort of) a canonical form for these? I admit I am not completely sure right now: can we associate a conjugacy class of subgroups of S_n, isomorphic to the Weyl group, in a sensible way to a finite Cartan type? > GAP's library of transitive groups provides a reasonable source of > small groups in this sense. Thanks for the hint, I'll have a look! Best, Martin _______________________________________________ Forum mailing list [email protected] https://mail.gap-system.org/mailman/listinfo/forum
