Comment (by ncohen):
Yo !
> Hmm, do you mean to construct the Cartesian product of fields? Then it
will be a ring, with two operations, addition and multiplication...
Hmmmm.. Well, I guess it may not be very hard to do.
1) A ring is a additive group (so the + is already implemented) for the
product of rings
2) It has a multiplicative operation, but perhaps the product of
multiplicative associative magma is not detected as such. If you can just
give Sage the right inheritances, perhaps you have no real code to
implement.
Good luck,
Nathann
