Let be a primitive polytope with eight vertices. Then there is a unimodular map that maps to the polyhedron whose vertices are (0, 0, 0), (1, 0, 0), (0, 1, 0), (0, 0, 1), (0, 1, 1), (1, , ), (1, , ), and (1, , ) with , , and . Furthermore, any primitive polyhedron with fewer than eight vertices can be embedded in one with eight vertices.
