Triangular trioprism

The triangular duoprism or trittip is a convex uniform trioprism that consists of 9 triangular duoprismatic prisms. It is the simplest possible trioprism.

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