G. C. Greubel, Table of n, a(n) for n = 0..371
FORMULA
From G. C. Greubel, Sep 26 2018: (Start)
a(n) = 29^n * Hermite(n, 7/29).
E.g.f.: exp(14*x - 841*x^2).
a(n) = numerator(Sum_{k=0..floor(n/2)} (-1)^k*n!*(14/29)^(n-2*k)/(k!*(n-2*k)!)). (End)
EXAMPLE
Numerators of 1, 14/29, -1486/841, -67900/24389, 6547756/707281,...
