Triangular trioprism

The triangular trioprism or trittip is a convex uniform trioprism that consists of 9 triangular duoprismatic prisms as facets. 6 facets join at each vertex. It is the simplest possible trioprism. It is also the 9-2-4 gyropeton.

The triangular trioprism can be vertex-inscribed into a pentacontatetrapeton.

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