Is there a way to change the generators used in the internal representation of the unit group of a number field? I am currently doing this by hand in an ad-hoc manner and it is very tedious, not to mention prone to mistakes. To be concrete, consider the following:
sage: CyclotomicField(5).unit_group().gens() [-zeta5, zeta5^3 + zeta5] I would rather the fundamental unit be real (so multiplied by zeta3), so that it is -zeta5^3 - zeta5^2 - 1 In particular, it needs to work with .log and .exp, and I need to be able to act on the group elements with field automorphisms. In case it matters, I am using Sage 4.3.0.
