# Small rhombihexahedral prism

The **small rhombihexahedral prism** or **srohp** is a prismatic uniform polychoron that consists of 2 small rhombihexahedra, 12 cubes, and 6 octagonal prisms. Each vertex joins 1 small rhombihexahedron, 2 cubes, and 2 octagonal prisms. As the name suggests, it is a prism based on the small rhombihexahedron.

Its vertex figure matches that of the chasmic cuboctachoron; while the equilateral triangles still correspond to cubes, the butterfly and isosceles triangles now correspond to the blend of 2 octagonal prisms' vertex figures.

## Vertex coordinatesEdit

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