The octagonal duotruncatoprism is a convex isogonal polychoron and the sixth member of the duoexpandoprisms that consists of 16 dioctagonal prisms, 64 rectangular trapezoprisms, 128 wedges and 64 tetragonal disphenoids obtained as the convex hull of two orthogonal octagonal-hexadecagonal duoprisms.
