%F G.f.: x^63/(1-x)^64.

%F E.g.f.: x^63*exp(x)/63!. (End)

%F From _Amiram Eldar_, Dec 17 2020: (Start)

%F Sum_{n>=63} 1/a(n) = 63/62.

%F Sum_{n>=63} (-1)^(n+1)/a(n) = A001787(63)*log(2) - A242091(63)/62! = 290536219160925437952*log(2) - 23620045751782378911483133238094693227021389 / 117288381359406970983270 = 0.9848351324... (End)
