Decagonal-dodecagonal duoprism

The 10-12 duoprism is a uniform duoprism that consists of 10 dodecagonal prisms, 12 decagonal prisms and 120 vertices.

This polychoron can be alternated into a 5-6 duoantiprism, although it cannot be made uniform. The dodecagons can also be alternated into long ditrigons to create a bialternatosnub 5-6 duoprism, which is also nonuniform.
