The truncated octahedral prism (OBSA: tope) is a prismatic uniform polychoron that consists of 2 truncated octahedra, 6 cubes, and 8 hexagonal prisms. Each vertex joins 1 truncated octahedron, 1 cube, and 2 hexagonal prisms. As the name suggests, it is a prism based on the truncated octahedron. As such it is also a convex segmentochoron (designated K4.89 on Richard Klitzing's list).
This polychoron can be alternated into a pyritohedral icosahedral antiprism, although it cannot be made uniform.

Representations[edit  edit source]
A truncated octahedral prism has the following Coxeter diagrams:
 x o4x3x () (full symmetry)
 x x3x3x () (bases have A_{3} symmetry)
 s2s4x3x () (bases have A_{3} symmetry, as snub)
 oo4xx3xx&#x (bases considered separately)
 xx3xx3xx&#x (bases separately under A_{3})
