Decagonal-dodecagonal duoprismatic prism

The decagonal-dodecagonal duoprismatic prism or datwip, also known as the decagonal-dodecagonal prismatic duoprism, is a convex uniform duoprism that consists of 2 decagonal-dodecagonal duoprisms, 10 square-dodecagonal duoprisms and 12 square-decagonal duoprisms.

This polyteron can be alternated into a pentagonal-hexagonal duoantiprismatic antiprism, although it cannot be made uniform. The octagons can also be alternated into long rectangles to create a pentagonal-hexagonal prismatic prismantiprismoid, which is also nonuniform.
