Enneagonal-truncated dodecahedral duoprism

The enneagonal-truncated dodecahedral duoprism or etid is a convex uniform duoprism that consists of 9 truncated dodecahedral prisms, 12 enneagonal-decagonal duoprisms, and 20 triangular-enneagonal duoprisms. Each vertex joins 2 truncated dodecahedral prisms, 1 triangular-enneagonal duoprism, and 2 enneagonal-decagonal duoprisms.

Vertex coordinates
The vertices of an enneagonal-truncated dodecahedral duoprism of edge length 2sin(π/9) are given by all even permutations of the last three coordinates of: where j = 2, 4, 8.
