Heptagonal-truncated dodecahedral duoprism

The heptagonal-truncated dodecahedral duoprism or hetid is a convex uniform duoprism that consists of 7 truncated dodecahedral prisms, 12 heptagonal-decagonal duoprisms and 20 triangular-heptagonal duoprisms. Each vertex joins 2 truncated dodecahedral prisms, 1 triangular-heptagonal duoprism, and 2 heptagonal-decagonal duoprisms.

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