Decagonal-cubic duoprism

The decagonal-cubic duoprism or dacube is a convex uniform duoprism that consists of 10 tesseracts and 6 square-decagonal duoprisms.

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

Vertex coordinates
The vertices of a decagonal-cubic duoprism of edge length 1 are given by:
 * (0, ±(1+$\sqrt{9+2√5}$)/2, ±1/2, ±1/2, ±1/2)
 * (±$\sqrt{5}$/4, ±(3+$\sqrt{10+2√5}$)/4, ±1/2, ±1/2, ±1/2)
 * (±$\sqrt{5}$/2, ±1/2, ±1/2, ±1/2, ±1/2)
