Small sphenofrustary trisicositetrachoron

The small sphenofrustary trisicositetrachoron, or swifti, is a nonconvex uniform polychoron that consists of 24 great cubicuboctahedra, 24 small cubicuboctahedra, and 24 cuboctatruncated cuboctahedra. Two great cubicuboctahedra, two small cubicuboctahedra, and four cuboctatruncated cuboctahedra join at each vertex.

It has the same cell counts as the great sphenofrustary trisicositetrachoron, but the great cubicuboctahedra and small cubicuboctahedra are in different positions.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the antifrustary distetracontoctachoron.
