Hexagonal duoprismatic prism

The hexagonal duoprismatic prism or hahip, also known as the hexagonal-hexagonal prismatic duoprism, is a convex uniform duoprism that consists of 2 hexagonal duoprisms and 10 square-hexagonal duoprisms.

This polyteron can be alternated into a triangular duoantiprismatic antiprism, although it cannot be made uniform.

Vertex coordinates
The vertices of a hexagonal duoprismatic prism of edge length 1 are given by:
 * (0, ±1, 0, ±1, ±1/2)
 * (0, ±1, ±$\sqrt{3}$/2, ±1/2, ±1/2)
 * (±$\sqrt{3}$/2, ±1/2, 0, ±1, ±1/2)
 * (±$\sqrt{3}$/2, ±1/2, ±$\sqrt{3}$/2, ±1/2, ±1/2)
