FORMULA
From G. C. Greubel, Nov 09 2018: (Start)
G.f.: x^80/(1-x)^81.
E.g.f.: x^80*exp(x)/80!. (End)
From Amiram Eldar, Dec 18 2020: (Start)
Sum_{n>=80} 1/a(n) = 80/79.
Sum_{n>=80} (-1)^n/a(n) = A001787(80)*log(2) - A242091(80)/79! = 48357032784585166988247040*log(2) - 3397298872212344557925469166982017642113449232981882085888 / 101355810171231196598821163455095 = 0.9879450412... (End)
