%N Central binomial coefficient A001405(n) divided by its characteristic cube divisor A056201(n).

%F a(n) = A001405(n)/A056059(n)^3 = binomial(n, floor(n/2)/A056059(n)^3 = A001405(n)/A056201(n).

%e n=14, binomial(14,7) = 3432 and A056059(14) = 2, thus a(14) = 3432/(2*2*2) = 429.

%Y Cf. A001405, A056056-A056060, A056201.
