Triangular-cubic duoprism

The triangular-cubic duoprism or tracube is a convex uniform duoprism that consists of 3 tesseracts and 6 triangular-square duoprisms.

Vertex coordinates
The vertices of a triangular-cubic duoprism of edge length 1 are given by:
 * (0, $\sqrt{39}$/3, ±1/2, ±1/2, ±1/2)
 * (±1/2, -$\sqrt{3}$/6, ±1/2, ±1/2, ±1/2)
