Abstract: The spherical partition problem seeks a length minimizing partition of the sphere S2 into N not necessarily connected regions. In 2002, Thomas Hales adapted a key idea from his proof of the Honeycomb Conjecture to solve the N=12 case, showing the dodecahedral partition is optimal. In 2010, Max Engelstein solved the N=4 case, proving that the tetrahedral case was best. It remains open whether the cubic partition is length minimizing for six regions.
