This large hollow cluster shape is built from 5mm neodymium ball magnets and uses 2 fundamental units: a solid interlocked pentagonal one of 21 balls (in gold) and a solid interlocked square one of 17 balls. 5 of the square units fit around the pentagonal unit to make each mini hemisphere subunit of 106 balls, 6 of which interconnected form each of 12 larger hemispheres. These 12 hemispheres interconnected in turn form a mega cluster sphere.
A total of 6 × 12 = 72 pentagonal units, and 5 × 6 × 12 = 360 square units.
A total magnet count of the 72 mini hemisphere mega cluster of:
17 × 5 + 21 = 106, 106 × 6 × 12 = 7632 magnetic balls.
2 large hemispheres of 6 subunits each can be easily connected as shown to make a smaller sphere of 12 × 106 = 1272 balls.
The full 72 mini hemisphere cluster is a lot trickier to build but once completed it is very strong, because the units used to make it are solid (in compact form).
If you look closely at this structure you can find fractal quasi self-similarity (partial but not exactly identical) among 3 levels of scale that resemble the geometry of a rhombic triacontahedron (a 30 diamond sided polyhedron). There are also symmetrical gaps formed among the units that make the whole structure look weirder.
