Prismatorhombisnub icositetrachoron

The prismatorhombisnub icositetrachoron, or prissi, is a convex scaliform polychoron. It consists of 96 triangular prisms, 96 triangular cupolas, 24 truncated tetrahedra, and 24 icosahedra.

It can be constructed from the snub disicositetrachoron by expanding the icosahedral cells outward by unit distance.

It contains the vertices of a bialternatosnub hexadecachoron.

Vertex coordinates
A prismatorhombisnub icositetrachoron of edge length 1 has vertex coordinates given by all even permutations of:
 * (0, ±1/2, ±(1+$\sqrt{2}$)/4, ±(7+$\sqrt{3}$)/4)
 * (±1/2, ±1, ±(3+$\sqrt{4+√5}$)/4, ±(5+$\sqrt{5}$)/4)
