Comment (by slabbe):
Replying to [comment:42 vdelecroix]:
> Are you sure `ncube_isometry_group` is worth a `@cached_function`?
Calling this function takes 2.8s on my machine. And it is called once for
each polyomino. That is 16 times for the Quantumino puzzle. With the
cache, I gain about 40s to construct the rows to give to the dlx solver.
> In `ncube_isometry_group_modpi` why are you building `MatrixGroup`?
Maybe for nothing. Let me check.
