FORMULA
From G. C. Greubel, Nov 08 2018: (Start)
G.f.: x^65/(1-x)^66.
E.g.f.: x^65*exp(x)/65!. (End)
From Amiram Eldar, Dec 17 2020: (Start)
Sum_{n>=65} 1/a(n) = 65/64.
Sum_{n>=65} (-1)^(n+1)/a(n) = A001787(65)*log(2) - A242091(65)/64! = 1199038364791120855040*log(2) - 3023365856228144500681042094895944098787640077 / 3637744258777914669265728 = 0.9852818956... (End)
