Description

(split out from #30169)

We give ExtPowerFreeModule the additional structure of a quotient module of TensorFreeModule.

For degrees 0 and 1 (for which this class is not instantiated by FiniteRankFreeModule.exterior_power), taking the quotient is trivial but we still set it up as a quotient for didactical/uniformity/formal reasons.

Shouldn't #30251 be a dependency of this ticket?

comment:6 Changed 15 months ago by mkoeppe

Yes, I will rebase this branch on top of it.
