Tetrahedral prism

The tetrahedral prism or tepe is a prismatic uniform polychoron that consists of 2 tetrahedra and 4 triangular prisms. Each vertex joins 1 tetrahedron and 3 triangular prisms. As the name suggests, it is a prism based on a tetrahedron, and as such is also a segmentochoron (designated K-4.9 in Richard Klitzing's list)..

Vertex coordinates
The vertices of a tetrahedral prism of edge length 1 are given by all even sign changes of the first three coordinates of:
 * ($\sqrt{2}$/4, $\sqrt{10}$/4, $\sqrt{6}$/4, ±1/2)
