Dodecagonal duoprism

The 12-12 duoprism is a noble uniform duoprism that consists of 24 dodecagonal prisms and 144 vertices. It is also the 24-11 gyrochoron.

This polychoron can be alternated into a 6-6 duoantiprism, although it cannot be made uniform. Twelve of the dodecagons can also be alternated into long ditrigons to create a bialternatosnub 6-6 duoprism, which is also nonuniform.

Vertex coordinates
The vertices of a 12-12 duoprism of edge length 1, centered at the origin, are given by:
 * (±(1+$\sqrt{3}$)/2, ±(1+$\sqrt{3}$)/2, ±(1+$\sqrt{3}$)/2, ±(1+$\sqrt{3}$)/2)
 * (±1/2, ±(2+$\sqrt{3}$)/2, ±1/2, ±(2+$\sqrt{3}$)/2)
 * (±1/2, ±(2+$\sqrt{3}$)/2, ±(2+$\sqrt{3}$)/2, ±1/2)
 * (±(2+$\sqrt{3}$)/2, ±1/2, ±1/2, ±(2+$\sqrt{3}$)/2)
 * (±(2+$\sqrt{3}$)/2, ±1/2, ±(2+$\sqrt{3}$)/2, ±1/2)
