Comment (by jmantysalo):
I am worried about how this should be defined. One possible definition is
that `L=[len(x) for x in P.level_sets()]` equals to `[len(x) for x in
P.dual().level_sets()]`. Another is that `L` equals to `reversed(L)`.
Coding errors are in a sense easy to fix, like giving correct answer.
Wrong definition is like asking wrong question.
