Triangular-great rhombicuboctahedral duoprism

The triangular-great rhombicuboctahedral duoprism or tragirco is a convex uniform duoprism that consists of 3 great rhombicuboctahedral prisms, 6 triangular-octagonal duoprisms, 8 triangular-hexagonal duoprisms and 12 triangular-square duoprisms. Each vertex joins 2 great rhombicuboctahedral prisms, 1 triangular-square duoprism, 1 triangular-hexagonal duoprism, and 1 triangular-octagonal duoprism. It is a duoprism based on a triangle and a great rhombicuboctahedron, which makes it a convex segmentoteron.

Vertex coordinates
The vertices of a triangular-great rhombicuboctahedral duoprism of edge length 1 are given by all permutations of the last three coordinates of:
 * $$\left(0,\,\frac{\sqrt3}3,\,±\frac{1+2\sqrt2}{2},\,±\frac{1+\sqrt2}{2},\,±\frac12\right),$$
 * $$\left(±\frac12,\,-\frac{\sqrt3}6,\,±\frac{1+2\sqrt2}{2},\,±\frac{1+\sqrt2}{2},\,±\frac12\right).$$
