Comment (by ncohen):
> That's not what you're asking sage to do. You're asking for a finite
abelian group, written additively, that happens to be cyclic of order 5.
If you know your group is going to be cyclic, you'd probably be better off
asking for a cyclic group explicitly.
Well. I want an additive Cyclic group. How can I build that ? This was my
original problem, and I was told AdditiveAbelianGroup was the way to
obtain it.
> So I'd agree with Volker that lists are more natural here.
If there exists an Additive Cyclic group somewhere, I agree.
> At the same time you're asking for conversion, which is supposed to make
a best effort, so adding a special case wouldn't be out of the question,
even if it's an ugly special case.
I'm sorry if it is ugly. I really don't know these classes and they are
all using each other, so I am always afraid something wrong might happen
somewhere `:-/`
