 Compound of two great icosahedra

The compound of two great icosahedra is a geometric figure formed by the intersection and arrangement of two great icosahedra in space. A great icosahedron is a type of polyhedron that is a dual of the standard (or regular) icosahedron. It can be visualized as a star-shaped figure with multiple vertices. When two great icosahedra are combined, their vertices and faces intersect in a symmetrical manner, creating a complex geometric structure.
