Hexagonal duoprism

The 6-6 duoprism is a noble uniform duoprism that consists of 12 hexagonal prisms and 36 vertices. It is also the 12-5 gyrochoron and the third in a series of triangular dihedral swirlchora.

This polychoron can be alternated into a 3-3 duoantiprism, although it cannot be made uniform. The dodecagons can also be alternated into long rectangles to create a bialternatosnub 3-6 duoprism, which is also nonuniform.
