12463,Polyhedron intersection and equality inconsistencies,lftabera,mhampton,"First of all, polyhedron __eq__ documentation is wrong. It states
{{{
def __eq__(self, other):
""""""
Test whether ``self`` is a strict sub-polyhedron of ``other``.
}}}
This does not correspond with the actual code nor the test.
Morevover, intersection of polyhedra produces output with wrong internal representation.
