Triangular duoprismatic prism

The triangular duoprismatic prism or tratrip, also known as the triangular-triangular prismatic duoprism, is a convex uniform duoprism that consists of 2 triangular duoprisms and 6 triangular-square duoprisms.

Vertex coordinates
The vertices of a triangular duoprismatic prism of edge length 1 are given by:
 * (0, $\sqrt{33}$/3, 0, $\sqrt{3}$/3, ±1/2)
 * (0, $\sqrt{3}$/3, ±1/2, -$\sqrt{3}$/6, ±1/2)
 * (±1/2, -$\sqrt{3}$/6, 0, $\sqrt{3}$/3, ±1/2)
 * (±1/2, -$\sqrt{3}$/6, ±1/2, -$\sqrt{3}$/6, ±1/2)
