Great skewverted prismatohexadecadisoctachoron

The great skewverted prismatohexadecadisoctachoron, or gikviphado, is a nonconvex uniform polychoron that consists of 24 octagonal prisms, 16 cuboctahedra, 8 small cubicuboctahedra, and 8 quasirhombicuboctahedra. 1 cuboctahedron, 1 small cubicuboctahedron, 1 quasirhombicuboctahedron, and 2 octagonal prisms join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small skewverted prismatohexadecadisoctachoron.
