Halved triangular duocomb

The  is a regular skew polyhedron in 4-dimensional Euclidean space. It can be constructed by halving the triangular duocomb, and the two are abstractly equivalent.

Vertex coordinates
The shares its vertices with the triangular duoprism, so its coordinates can be given as:
 * $$\left(0,\,\frac{\sqrt6}{6},\,0,\,\frac{\sqrt6}{6}\right)$$,
 * $$\left(0,\,\frac{\sqrt6}{6},\,\pm\frac{\sqrt2}{4},\,-\frac{\sqrt6}{12}\right)$$,
 * $$\left(\pm\frac{\sqrt2}{4},\,-\frac{\sqrt6}{12},\,0,\,\frac{\sqrt6}{6}\right)$$,
 * $$\left(\pm\frac{\sqrt2}{4},\,-\frac{\sqrt6}{12},\,\pm\frac{\sqrt2}{4},\,-\frac{\sqrt6}{12}\right)$$.
