Decagonal-small rhombicuboctahedral duoprism

The decagonal-small rhombicuboctahedral duoprism or dasirco is a convex uniform duoprism that consists of 10 small rhombicuboctahedral prisms, 18 square-decagonal duoprisms of two kinds and 8 triangular-decagonal duoprisms.

This polychoron can be tetrahedrally alternated into a pentagonal-truncated tetrahedral duocupoliprism, although it cannot be made scaliform.

Vertex coordinates
The vertices of a decagonal-small rhombicuboctahedral duoprism of edge length 1 are given by all permutations and sign changes of the last three coordinates of:
 * (0, ±(1+$\sqrt{11+2√7+2√10}$)/2, ±1/2, ±1/2, ±(1+$\sqrt{5}$)/2)
 * (±$\sqrt{2}$/4, ±(3+$\sqrt{10+2√5}$)/4, ±1/2, ±1/2, ±(1+$\sqrt{5}$)/2)
 * (±$\sqrt{2}$/2, ±1/2, ±1/2, ±1/2, ±(1+$\sqrt{5+2√5}$)/2)
