Octagonal-dodecagonal duoprism

The 8-12 duoprism is a uniform duoprism that consists of 8 dodecagonal prisms, 12 octagonal prisms and 96 vertices.

This polychoron can be alternated into a 4-6 duoantiprism, although it cannot be made uniform. The octagons can also be alternated into long rectangles to create a bialternatosnub 6-4 duoprism and the dodecagons into long ditrigons to create a bialternatosnub 4-6 duoprism, which are also both nonuniform.
