G. C. Greubel, Table of n, a(n) for n = 0..500
Index entries for linear recurrences with constant coefficients, signature (29,29,29,29,29,29,29,29,29,29,-435).
FORMULA
G.f.: (t^11 + 2*t^10 + 2*t^9 + 2*t^8 + 2*t^7 + 2*t^6 + 2*t^5 + 2*t^4 + 2*t^3 + 2*t^2 + 2*t + 1)/(435*t^11 - 29*t^10 - 29*t^9 - 29*t^8 - 29*t^7 - 29*t^6 - 29*t^5 - 29*t^4 - 29*t^3 - 29*t^2 - 29*t + 1).
From G. C. Greubel, Jul 25 2024: (Start)
a(n) = 29*Sum_{j=1..10} a(n-j) - 435*a(n-11).
G.f.: (1+x)*(1-x^11)/(1 - 30*x + 464*x^11 - 435*x^12). (End)
