G. C. Greubel, Table of n, a(n) for n = 0..428
FORMULA
From G. C. Greubel, Jul 16 2018: (Start)
a(n) = 12^n * Hermite(n, 11/24).
E.g.f.: exp(11*x - 144*x^2).
a(n) = numerator(Sum_{k=0..floor(n/2)} (-1)^k*n!*(11/12)^(n-2*k)/(k!*(n-2*k)!)). (End)
EXAMPLE
Numerators of 1, 11/12, -167/144, -8173/1728, 54385/20736, ...
