FORMULA
From G. C. Greubel, Nov 12 2018: (Start)
G.f.: x^89/(1-x)^90.
E.g.f.: x^89*exp(x)/89!. (End)
From Amiram Eldar, Dec 20 2020: (Start)
Sum_{n>=89} 1/a(n) = 89/88.
Sum_{n>=89} (-1)^(n+1)/a(n) = A001787(89)*log(2) - A242091(89)/88! = 27544165874099711116505513984*log(2) - 19273610318617028543535699052712169302368266227220008435756217833 / 1009503869305462718124258788012746200 = 0.9891254514... (End)
