Small spinofrustary trisicositetrachoron

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

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

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