The **small rhombihexahedron**, or **sroh**, is a uniform polyhedron. It consists of 12 squares and 6 octagons. Two squares and two octagons meet at each vertex. It also has 8 triangular pseudofaces and 6 square pseudofaces.

It is a faceting of the small rhombicuboctahedron, using 12 of its squares, along with the 6 octagons of the small cubicuboctahedron.

It can be constructed as a blend of three orthogonal octagonal prisms, with 6 pairs of coinciding square faces blending out.

## Vertex coordinates[edit | edit source]

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

## Related polyhedra[edit | edit source]

The rhombisnub hyperhombihedron is a uniform polyhedron compound composed of 5 small rhombihexahedra.
