The **small retrospinoprismatodisicositetrachoron**, or **sarnipadi**, is a nonconvex uniform polychoron that consists of 24 truncated cubes, 24 small rhombihexahedra, and 96 triangular prisms. Four truncated cubes, four small rhombihexahedra, and four triangular prisms join at each vertex.

It can be constructed as a blend of three small pseudorhombic prismatotesseracts. In the process the octagonal prisms blend into small rhombihexahedra.

## Vertex coordinates[edit | edit source]

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