It's a truncated cuboctahedron on the outside, and a rhombicuboctahedron on the inside, and the two are connected by the cubes. Using this composition, the numbers of rods, spheres, and panels may be quickly counted up: * 12 pink cubes: 12 x [ 12 pink rods, 6 pink squares, 4 spheres + 4 spheres / shared by 2 cubes ] = 144 rods & 72 squares & 72 spheres * 24 blue triangles: 24 x [ 1 blue rod , 1 blue triangle, 0 spheres ] = 24 rods & 24 triangles Totals given in the summary box.
