The **prismatofaceted tetracontoctidisicositetrachoron**, or **pifficdi**, is a nonconvex uniform polychoron that consists of 48 octahedra, 24 truncated cubes, 24 small rhombihexahedra, and 96 triangular prisms. Two octahedra, four truncated cubes, four small rhombihexahedra, and four triangular prisms join at each vertex.

It has the same cell counts as the diretroprismatodisicositetritetracontoctachoron, but the small rhombihexahedra and triangular prisms are in different positions.

## Vertex coordinates[edit | edit source]

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