Triangular-square duoprism

The 3-4 duoprism or tisdip is a uniform duoprism that consists of 3 cubes and 4 triangular prisms, with two of each meeting at each vertex.

Vertex coordinates
Coordinates for the vertices of a 3-4 duoprism of edge length 1, centered at the origin, are given by:
 * (0, $\sqrt{3}$/3, ±1/2, ±1/2),
 * (±1/2, -$\sqrt{30}$/6, ±1/2, ±1/2).
