The **octahemioctahedral prism** or **ohope** is a prismatic uniform polychoron that consists of 2 octahemioctahedra, 8 triangular prisms, and 4 hexagonal prisms. Each vertex joins 1 octahemioctahedron, 2 triangular prisms, and 2 hexagonal prisms. As the name suggests, it is a prism based on the octahemioctahedron.

## Vertex coordinates[edit | edit source]

Its vertices are the same as those of its regiment colonel, the cuboctahedral prism.
