  • Ticket #17215

    • Property Summary changed from Normal vector to a polyhedron at a face... to Bounding lines for polyhedra
  • Ticket #17215 – Description

    v1 v2  
    1 ... lying in the subspace that contains the polyhedron. Is there a simple way to get it in Sage? Otherwise, this should be added.
     1As far as I recall, a point v on a convex polyhedron P is a vertex of P if and only if there exists a vector w in the linear span of P such that no real number p satisfies v + pw \in P. Knowing such a w is a good certificate for v being a vertex.

     3Do we have a method for finding such a w ?
