Hendecagonal duotruncatoprism

The hendecagonal duotruncatoprism is a convex isogonal polychoron and the ninth member of the duotruncatoprism family. It consists of 22 dihendecagonal prisms, 121 rectangular trapezoprisms, 242 wedges, and 121 tetragonal disphenoids. 2 dihendecagonal 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 hendecagonal-icosidigonal duoprisms whose icosidigonal prisms have a smaller radius than thei hendecagonal prisms. However, it cannot be made uniform.
