Square tettene

The square tettene or squete, also known as the triangular-square disphenoid, is a convex CRF polyteron with 3 square scalenes, 4 pentachora and 7 vertices. Along with the hexateron (considered as a triangular disphenoid), they are the only convex equilateral disphenoids in 5-dimensional space.

Vertex coordinates
The vertices of a square tettene with unit edge length are given by:
 * (0, $\sqrt{3}$/3, 0, 0, $\sqrt{6}$/12),
 * (±1/2, -$\sqrt{3}$/6, 0, 0, $\sqrt{6}$/12),
 * (0, 0, ±1/2, ±1/2, -$\sqrt{6}$/12).
