Comment (by darij):
Thanks for taking care of this. The dependency is gone indeed. Could you
maybe also document the choice of multiplication order in the (module)
documentation? And while at that:
{{{
A semimonomial transformation group over a ring `R` of length `n` is equal
to
the semidirect product of the monomial transformation group
(also known as the complete monomial group) and the group of ring
automorphisms.
]}}
either it should be "The semimonomial...", not "A semimonomial...", or it
should be "a group of ring automorphisms", not "the group of ring
automorphisms". In general, it should be impossible to compute the group
of all automorphisms of a ring, so I suspect it's either "a group" or you
are only considering finite fields?
