Dodecagonal duotruncatoalterprism

The dodecagonal duotruncatoalterprism is a convex isogonal polychoron and the eleventh member of the duotruncatoalterprism family. It consists of 24 dodecagonal prisms, 48 dodecagonal cupolas, 144 rectangular trapezoprisms, and 144 tetragonal disphenoids. 1 dodecagonal prism, 3 dodecagonal cupolas, 2 rectangular trapezoprisms, and 1 tetragonal disphenoid join at each vertex. It can be obtained as the convex hull of two orthogonal dodecagonal-didodecagonal duoprisms. However, it cannot be made scaliform.
