Square-dodecagonal duoprism

The 4-12 duoprism is a uniform duoprism that consists of 4 dodecagonal prisms, 12 square prisms and 48 vertices.

This polychoron can be alternated into a 2-6 duoantiprism, although it cannot be made uniform. The dodecagons can also be alternated into long ditrigons to create a bialternatosnub 2-6 duoprism, which is also nonuniform.
