%N Number of symmetrically inequivalent coincidence rotations of index n in lattice A_4.
%C The overall number of coincidence rotations is 120 times higher. Some symmetrically distinct rotations generate the same coincidence site lattices, hence a(n) >= A331142(n). - _Andrey Zabolotskiy_, Jan 29 2020
