In version 8.9 there will be CombinatorialPolyhedron, which can be initialized with a list of facets, as

CombinatorialPolyhedron([[1,2], [2,3], [3,4], [4,1]])

With this object you have a face iterator, the face lattice and some other methods. I don't know if that helps.

This is also available in the develop branch.
