  • Ticket #26922 – Description

    initial v11  
     1#28625 fixed the `f_vector` in the case of unpointed polyhedra/polyhedra with lines.
     2
     3We add doctests showing that #28625 fixed a bug in `f_vector`.
     4
     5Before:
    16{{{
    27sage: Polyhedron(ieqs=[[1,-1,0],[1,1,0]]).f_vector()
    38(1, 2, 1)
    49}}}
    5 This polyhedron does not have zero-dimensional faces, does it?
     10
     11But this polyhedron does not have zero-dimensional faces, and #28625 has correctly changed that:
     12{{{
     13sage: Polyhedron(ieqs=[[1,-1,0],[1,1,0]]).f_vector()
     14(1, 0, 2, 1)
     15}}}
     16
     17Also we add documentation, specifically warning users that the methods
     18- `vertices`,
     19- `vertices_list`,
     20- `vertices_generator`
     21- `vertices_matrix`,
     22- `n_vertices`,
     23treat vertices of the `Vrepresentation` and not vertices of the polyhedron in the unpointed case.
