Cuboctahedron 30 Compound, Solid

This is a solid model of a compound of 30 cuboctahedra with icosahedral edge symmetry,  made by joining a cubeoctahedron whose 4-fold symmetry axis is aligned with the edge center of an icosahedron (or dodecahedron) to a similar one aligned with every other edge.The original cuboctahedraon was rotated .0812 radians to produce this model, similar to the one on Marcel Tunnessen's website, denoted as "30B | A5 x I / C2 x I | μ.
