Snub pseudosnub rhombicosahedron

The snub pseudosnub rhombicosahedron, sapisseri, or compound of twenty tetrahemihexahedra is a uniform polyhedron compound. It consists of 20+60 triangles and 60 squares. The vertices coincide in pairs, and thus four triangles and four squares join at each vertex.

This compound can be formed by replacing each octahedron in the disnub icosahedron with the tetrahemihexahedron with which it shares its edges. Therefore, it also has the same edges as the great dirhombicosidodecahedron, although it is chiral, unike either the great dirhombicosidodecahedron or disnub iosahedron.

It can be constructed as a blend of the great dirhombicosidodecahedron and the great snub dodecicosidodecahedron.

Its quotient prismatic equivalent is the tetrahemihexahedral icosayodakoorthowedge, which is 22-dimensional.
