%N Characteristic cube divisor (A056191) of central binomial coefficient (A001405).
%F a(n) = A056059(n)^3 = g^3 and binomial(n, floor(n/2)) = a(n)^3 * L^2 * A056060(n), where L = A056056(n)/A056059(n).
%e n=14, binomial(14,8) = 3432 = 2*2*2*3*11*13 so g(3432)=2, thus a(14)=8.
%Y Cf. A056056-A056060, A056202.
%Y Equals A056059^3.
