Yes, but I have no idea how to use sockets from an axiom domain. Do you? If so,
go ahead and show me a simple example. I can then adapt the domain.

Yes, I hope so too.

Hm, on my machine here it works just fine... Except that I need to parametrize
the domain, to allow for polytopes with vertices being floats or rational
numbers.
I grepped my polymake directory for "Illegal instruction" but got no
match. Where does this come from?
