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.

Vertex coordinates
The vertices of a triangular-hexagonal duoprismatic prism of edge length 1 are given by:
 * (0, $\sqrt{57}$/3, 0, ±1, ±1/2)
 * (0, $\sqrt{3}$/3, ±$\sqrt{3}$/2, ±1/2, ±1/2)
 * (±1/2, –$\sqrt{3}$/6, 0, ±1, ±1/2)
 * (±1/2, –$\sqrt{3}$/6, ±$\sqrt{3}$/2, ±1/2, ±1/2)
