Formula

From G. C. Greubel, Oct 29 2019: (Start)

G.f.: (10000000 + 1721088541*x + 20231030040*x^2 + 46811183311*x^3 + 26288037136*x^4 + 3118171011*x^5 + 35831800*x^6 + x^7)/(1-x)^8.

E.g.f.: (10000000 + 1791088541*x + 15383780643*x^2 + 29022110271*x^3 + 18775618400*x^4 + 4926550090*x^5 + 533239861*x^6 + 19487171*x^7)*exp(x). (End)
