%N Multiplications between idempotent equivalence classes for n X n matrices over GF(2).
%C With the n X n matrices over GF(2) construct 3-tuples (a,b,c) where a*b = c. Map each of the three elements to their idempotent under self multiplication. Filter on unique 3-tuples.
%Y The idempotents are enumerated in A132186.
