Abelian Extensions
New Features:
- New functionality to exploit the Galois-module properties of an
abelian extension of a normal field have been added. In particular it is
possible to create the corresponding cohomology module and thus compute
the low-dimensional cohomology groups explicitly.
- A function to directly enumerate absolutely normal subfields of
some suitable abelian extension has been provided.
