I think you forgot to tell the number of nodes for the above number. ;-) Well, it is clear that you don't want to reserve so much memory at once. But I don't have any idea how to do this nicely. That is the reason, why this mail also goes to axiom-developer. The problem is in aldor-combinat we have huge structures which are generated on the fly and generated on demand in a "Generator" structure. So we have a function structures: SetSpecies(L) -> Generator % The problem now is, if I call "g := structures(s)" inside an Axiom session, one cannot simply step this generator in a form like for x in g repeat {...} Is there somebody knowing the internals of Axiom (and maybe Aldor) who could help to make such a "for" statement work?
