Hexagonal-small rhombicuboctahedral duoprism

The hexagonal-small rhombicuboctahedral duoprism or hasirco is a convex uniform duoprism that consists of 6 small rhombicuboctahedral prisms, 18 square-hexagonal duoprisms of two kinds and 8 triangular-hexagonal duoprisms. Each vertex joins 2 small rhombicuboctahedral prisms, 1 triangular-hexagonal duoprism, and 3 square-hexagonal duoprisms.

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

Vertex coordinates
The vertices of a hexagonal-small rhombicuboctahedral duoprism of edge length 1 are given by all permutations of the last three coordinates of:
 * $$\left(0,\,±1,\,±\frac12,\,±\frac12,\,±\frac{1+\sqrt2}{2}\right),$$
 * $$\left(±\frac{\sqrt3}2,\,±\frac12,\,±\frac12,\,±\frac12,\,±\frac{1+\sqrt2}{2}\right).$$

Representations
A hexagonal-small rhombicuboctahedral duoprism has the following Coxeter diagrams:
 * x6o x4o3x (full symmetry)
 * x3x x4o3x (hexagons as ditrigons)
