Square-decagonal duoprism

The square-decagonal duoprism or squadedip, also known as the 4-10 duoprism, is a uniform duoprism that consists of 4 decagonal prisms, 10 cubes and 40 vertices.

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

Vertex coordinates
Coordinates for the vertices of a square-decagonal duoprism with edge length 1 are given by:
 * (±1/2, ±1/2, 0, ±(1+$\sqrt{5}$)/2),
 * (±1/2, ±1/2, ±$\sqrt{10+2√5}$/4, ±(3+$\sqrt{5}$)/4),
 * (±1/2, ±1/2, ±$\sqrt{5+2√5}$/2, ±1/2).
