Heptagonal-truncated icosahedral duoprism

The heptagonal-truncated icosahedral duoprism or heti is a convex uniform duoprism that consists of 7 truncated icosahedral prisms, 20 hexagonal-heptagonal duoprisms, and 12 pentagonal-heptagonal duoprisms. Each vertex joins 2 truncated icosahedral prisms, 1 pentagonal-heptagonal duoprism, and 2 hexagonal-heptagonal duoprisms.

Vertex coordinates
The vertices of a heptagonal-truncated icosahedral duoprism of edge length 2sin(π/7) are given by all even permutations of the last three coordinates of: where j = 2, 4, 6.
