Trapezohedron

A trapezohedron is a rank 3 antitegum. A $n$-gonal trapezohedron is a trapezohedron with 2$n$ faces.

Examples

 * If you consider the tetrahedron to be the digonal antiprism, then since it is self dual it is also a digonal trapezhedron.
 * The trigonal trapezohedra are the rhombohedra, they include the cube and two golden rhombohedra
