Square-hexagonal duoprism

The square-hexagonal duoprism or shiddip, also known as the 4-6 duoprism, is a uniform duoprism that consists of 4 hexagonal prisms, 6 cubes and 24 vertices.

This polychoron can be alternated into a digonal-triangular duoantiprism, although it cannot be made uniform.

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