Smaller giant icosahedra
Both icosahedron models shown in this page rest in a triangular face, and are made of six reinforced rhombicosidodecahedra (green rods), and six normal ones. The first one has edges made of two square antiprisms, which places the balls very near to one another, and make this a sort of dwarf giant icosahedron. Its scale is 5.92.

The edges of the second model are made of four square antiprisms. Its scale is 7.60.

Additional supports were required during the construction; they could be removed when it was finished:
