Dodecagonal-truncated icosahedral duoprism

The dodecagonal-truncated icosahedral duoprism or twati is a convex uniform duoprism that consists of 12 truncated icosahedral prisms, 20 hexagonal-dodecagonal duoprisms and 12 pentagonal-dodecagonal duoprisms.

Vertex coordinates
The vertices of a dodecagonal-truncated icosahedral duoprism of edge length 1 are given by all even permutations and all sign changes of the last three coordinates of:
