The small circumfacetodistetracontoctachoron, or smiffadic, is a nonconvex uniform polychoron that consists of 48 octahedra and 48 small rhombicuboctahedra. Two octahedra and eight small rhombicuboctahedra join at each vertex.

It also has triangular prisms as pseudofacets.

Vertex coordinates[edit | edit source]

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