Seiichi Manyama, Table of n, a(n) for n = 0..310
FORMULA
a(n) = 6^n/n! * Product_{k=0..n-1} (288*k - 1) for n > 0.
a(n) = -1728^n * Gamma(n - 1/288) / (288 * Gamma(287/288) * Gamma(n+1)). - Vaclav Kotesovec, Jun 14 2018
a(n) ~ -2^(6*n - 5) * 3^(3*n - 2) / (Gamma(287/288) * n^(289/288)). - Vaclav Kotesovec, Jun 16 2018
D-finite with recurrence: n*a(n) +6*(-288*n+289)*a(n-1)=0. - R. J. Mathar, Jan 17 2020
