This is definitely an example of where Sage and GAP differ in their
approaches, but this is more about subgroups/subactions... and there hasn't
been much discussion on this topic yet.
GAP evaluates subgroups/subactions without regard for the degree of the
original action. Thus, if you take your ty

Fine, I am now convinced that you are right - we do need more

Since I am still a bit paranoid about speed and memory consumption,

Abelian groups is second on my list (right after graphs + latex), but
as I've been told, "many have failed here." So I'd get out of the way
(or help) if anybody else is interested.
And I have a vested interest in permutation groups..

Indeed, somehow people who wrote the permutation groups code in Sage
kept forgetting that
a permutation group is a pair (G,X), where G is a group and X is a
set, on which G acts.
Once you think that you can get away with permutations alone, you are
doomed...

To summarize: Plain python cannot pickle inner classes or functions:

... class inner(object):
... pass
>>> o = outer()

(works)
>>> i = o.inner()
>>> pickle.dumps(i)

The work-around is to make the cone factory a top-level class (or

I tried "sage -ba" and the build now completes. Sage now starts without

Hi Volker,
That definitely makes sense, let me think a bit about it and then post
the comments/agreements.
You cannot pickle functions, so you cannot pass a factory to construct
cones (because you may need to have more cones later, so you need to

Hi Andrey,
I like the ToricLattice/ToricLatticeMorphism/FanMorphism, though I
would call the latter ToricMorphism. Domain/Codomain always reminds me
of "Cohomology Operations and Homology Cooperations" (Capter 17 in
Switzer) but if we want to use that nomenclature then thats fine with
