Octagonal duotransitionalterprism

The octagonal duotransitionalterprism is a convex isogonal polychoron and the sixth member of the duotransitionalterprism family. It consists of 16 octagonal trapezorhombihedra, 16 octagonal prisms, and 64 rectangular trapezoprisms. 2 octagonal trapezorhombihedra, 1 octagonal prism, and 2 rectangular trapezoprisms join at each vertex. It can be obtained as the convex hull of two orthogonal octagonal-hexadecagonal duoprisms. However, it cannot be made scaliform.
