Octagonal duotruncatoprism

The octagonal duotruncatoprism is a convex isogonal polychoron and the seventh member of the duotruncatoprism family. It consists of 16 dioctagonal prisms, 64 rectangular trapezoprisms, 128 wedges, and 64 tetragonal disphenoids. 2 dioctagonal prisms, 2 rectangular trapezoprisms, 3 wedges, and 1 tetragonal disphenoid join at each vertex. It can be obtained as the convex hull of two orthogonal octagonal-dioctagonal duoprisms whose dioctagonal prisms have a smaller circumradius than their octagonal prisms. However, it cannot be made uniform.
