Description

In #26887 we create a new class, that handles the calculations depending only on the combinatorial type much more quickly. This includes the following methods of the class Polyhedron:

  • face_lattice
  • faces
  • f_vector
  • vertex_graph
  • vertex_digraph (?)
  • neighborliness

Maybe adding new methods concerning flag-vector, h-Vector k-simplicial, k-neighborly etc.
