FORMULA
From G. C. Greubel, Nov 03 2018: (Start)
G.f.: x^67/(1-x)^68.
E.g.f.: x^67*exp(x)/67!. (End)
From Amiram Eldar, Dec 17 2020: (Start)
Sum_{n>=67} 1/a(n) = 67/66.
Sum_{n>=67} (-1)^(n+1)/a(n) = A001787(67)*log(2) - A242091(67)/66! = 4943727411754159833088*log(2) - 202565512367285681545811693791632836799528091007 / 59113344205141113375568080 = 0.9857030700... (End)
