Decagonal duotransitionalterprism

The decagonal duotransitionalterprism is a convex isogonal polychoron and the eighth member of the duotransitionalterprism family. It consists of 20 decagonal trapezorhombihedra, 20 decagonal prisms, and 100 rectangular trapezoprisms. 2 decagonal trapezorhombihedra, 1 decagonal prism, and 2 rectangular trapezoprisms join at each vertex. It can be obtained as the convex hull of two orthogonal decagonal-icosagonal duoprisms. However, it cannot be made scaliform.
