Triangular-hexagonal duoprismatic prism

The triangular-hexagonal duoprismatic prism or trahip, also known as the triangular-hexagonal prismatic duoprism, is a convex uniform duoprism that consists of 2 triangular-hexagonal duoprisms, 3 square-hexagonal duoprisms, and 6 triangular-square duoprisms. Each vertex joins 2 triangular-square duoprisms, 2 square-hexagonal duoprisms, and 1 triangular-hexagonal duoprism. Being a prism based on an orbiform polytope, it is also a convex segmentoteron.

Vertex coordinates
The vertices of a triangular-hexagonal duoprismatic prism of edge length 1 are given by:
 * $$\left(0,\,\frac{\sqrt3}3,\,0,\,±1,\,±\frac12\right),$$
 * $$\left(±\frac12,\,-\frac{\sqrt3}6,\,0,\,±1,\,±\frac12\right),$$
 * $$\left(0,\,\frac{\sqrt3}3,\,±\frac{\sqrt3}2,\,±\frac12,\,±\frac12\right),$$
 * $$\left(±\frac12,\,-\frac{\sqrt3}6,\,±\frac{\sqrt3}2,\,±\frac12,\,±\frac12\right).$$
