  • Ticket #29189 – Description

    initial v12  
    11This ticket migrates the methods `is_lawrence_polytope` and `is_pyramid` from `Polyhedron_base` to `CombinatorialPolyhedron`.
     2
     3Also, we change the output for the `0`-dimensional polyhedron. It is a pyramid over the empty polyhedron, even if it is not constructable in sage.
     4
     5Along the way we fix a small bug, where the trivial combinatorial polyhedron in dimension 0 was set up without vertices (and facets). The bug fix is tested by `CombinatorialPolyhedron(0).is_pyramid(certificate=True)`.
