Triangular-great rhombicosidodecahedral duoprism

The triangular-great rhombicosidodecahedral duoprism or tragrid is a convex uniform duoprism that consists of 3 great rhombicosidodecahedral prisms, 12 triangular-decagonal duoprisms, 20 triangular-hexagonal duoprisms, and 30 triangular-square duoprisms. Each vertex joins 2 great rhombicosidodecahedral prisms, 1 triangular-square duoprism, 1 triangular-hexagonal duoprism, and 1 triangular-decagonal duoprism. It is a duoprism based on a triangle and a great rhombicosidodecahedron, which makes it a convex segmentoteron.

Vertex coordinates
The vertices of a triangular-great rhombicosidodecahedral duoprism of edge length 1 are given by all permutations of the last three coordinates of: along with all even permutations of the last three coordinates of:
