Small icosihemidodecahedral prism

The small icosihemidodecahedral prism or seihiddip, is a prismatic uniform polychoron that consists of 2 small icosihemidodecahedra, 20 triangular prisms, and 6 decagonal prisms. Each vertex joins 1 small icosihemidodecahedron, 2 triangular prisms, and 2 decagonal prisms. As the name suggests, it is a prism based on the small icosihemidodecahedron.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the icosidodecahedral prism.
