Enneagonal-truncated icosahedral duoprism

The enneagonal-truncated icosahedral duoprism or eti is a convex uniform duoprism that consists of 9 truncated icosahedral prisms, 20 hexagonal-enneagonal duoprisms, and 12 pentagonal-enneagonal duoprisms. Each vertex joins 2 truncated icosahedral prisms, 1 pentagonal-enneagonal duoprism, and 2 hexagonal-enneagonal duoprisms.

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