    initial v21  
    33We fix this to return
    44- the `Digraph` on 0 vertices for the empty polyhedron and
    5 - the `Digraph` on 2 vertices with one edge for the 0-dimensional polyhedron (it was misbehaved even before #29188).
     5- the `Digraph` on 1 vertex for the 0-dimensional polyhedron (it was misbehaved even before #29188).
    66
    7 The vertex-facet-graph for the `0`-dimensional polyhedron is a bit tricky, as it doesn't have inequalities and `Polyhedron(([0])).combinatorial_polyhedron())` therefore lacks facet names.
     7We also "fix" the definition of facets to correspond to inequalities.
     8The `0`-dimensional polyhedron does not have facets in this case anymore.
     9(Before this ticket `n_facets` and `facets` would use different definitions of facets.)b
