Beyond the 32: Superconducting Pairing Channels of the Icosahedral Group — Classification, Approximant Branching, and Ginzburg–Landau Theory for Quasicrystals

A symmetry-based classification of superconducting order parameters is known for the 32 crystallographic point groups. The icosahedral group is the sole additional finite point group in three-dimensional space that occurs as an exact physical symmetry—in icosahedral quasicrystals...
