projectiveSpaceFan -- the fan of projective n space

Synopsis

Description

Generates the fan of projective $n$-space.

i1 : F = projectiveSpaceFan 2

o1 = {ambient dimension => 2         }
      number of generating cones => 3
      number of rays => 3
      top dimension of the cones => 2

o1 : Fan
i2 : apply(maxCones F, rays)

o2 = {| 1 -1 |, | 1 0 |, | -1 0 |}
      | 0 -1 |  | 0 1 |  | -1 1 |
