The great chirorhombidodecahedron, gikrid, or compound of six pentagrammic prisms is a uniform polyhedron compound. It consists of 30 squares and 12 pentagrams, with one pentagram and two squares joining at a vertex.
Its quotient prismatic equivalent is the pentagrammic prismatic hexateroorthowedge, which is eight-dimensional.
Vertex coordinates[edit | edit source]
The vertices of a great chirorhombidodecahedron of edge length 1 are given by all permutations of:
plus all even permutations of:
This compound is chiral. The compound of the two enantiomorphs is the great disrhombidodecahedron.
