Dodecagonal-square antiprismatic duoprism

The dodecagonal-square antiprismatic duoprism or twasquap is a convex uniform duoprism that consists of 12 square antiprismatic prisms, 2 square-dodecagonal duoprisms and 8 triangular-dodecagonal duoprisms.

Vertex coordinates
The vertices of a dodecagonal-square antiprismatic duoprism of edge length 1 are given by:
