Pentagonal duotruncatoalterprism

The pentagonal duotruncatoalterprism is a convex isogonal polychoron and the third member of the duotruncatoalterprism family. It consists of 10 pentagonal prisms, 20 pentagonal cupolas, 25 rectangular trapezoprisms, and 25 tetragonal disphenoids. 1 pentagonal prism, 3 pentagonal cupolas, 2 rectangular trapezoprisms, and 1 tetragonal disphenoid join at each vertex. obtained as the convex hull of two orthogonal pentagonal-decagonal duoprisms. However, it cannot be made scaliform.
