 Replying to [comment:8 jbandlow]:
 > Fixed.  The only change between the new patch and the previous one is
 line 1076 of modules_with_basis.py, in the `invert` method:

 self.codomain(),

 self.domain(),
 > }}}

 Yes, Adrien had noticed this, and was about to fix it in the Sage-Combinat
 queue. Since this patch is not yet in Sage, I agree that it's best to
 include the fix right away in it. Positive review!
