FORMULA
From G. C. Greubel, Jul 27 2016: (Start)
G.f.: x*(1 + 8209*x + 2268594*x^2 + 99205106*x^3 + 1285872575*x^4 + 6421628943*x^5 + 13985589372*x^6 + 13985589372*x^7 + 6421628943*x^8 + 1285872575*x^9 + 99205106*x^10 + 2268594*x^11 + 8209*x^12 + x^13)/(1 - x)^15.
E.g.f.: (1/2)*x*(2 + 8222*x + 789060*x^2 + 10391810*x^3 + 40075050*x^4 + 63436374*x^5 + 49329280*x^6 + 20912320*x^7 + 5135130*x^8 + 752752*x^9 + 66066*x^10 + 3367*x^11 + 91*x^12 + x^13)*exp(x). (End)
