The i-th entry of the f-vector of P is the number of dimension i-1 faces of P, so it starts with the number vertices, has dim(P)+1 entries, and the last entry is 1 for P itself. It is the same for a Cone C.
i1 : P = cyclicPolytope(3,5) o1 = {ambient dimension => 3 } dimension of lineality space => 0 dimension of polyhedron => 3 number of facets => 6 number of rays => 0 number of vertices => 5 o1 : Polyhedron |
i2 : fVector P o2 = {5, 9, 6, 1} o2 : List |
The object fVector is a method function.
