Triangular duotruncatoprism

The triangular duotruncatoprism is a convex isogonal polychoron and the first member of the duotruncatoprisms that consists of 6 ditrigonal prisms, 9 rectangular trapezoprisms, 18 wedges and 9 tetragonal disphenoids obtained as the convex hull of two orthogonal triangular-hexagonal duoprisms. However, it cannot be made uniform.
