G. C. Greubel, Table of n, a(n) for n = 0..500
Index entries for linear recurrences with constant coefficients, signature (16,16,16,16,16,16,16,16,16,16,-136).
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)/(136*t^11 - 16*t^10 - 16*t^9 - 16*t^8 - 16*t^7 - 16*t^6 - 16*t^5 - 16*t^4 - 16*t^3 - 16*t^2 - 16*t + 1).
From G. C. Greubel, Jul 23 2024: (Start)
a(n) = 16*Sum_{j=1..10} a(n-j) - 136*a(n-11).
G.f.: (1+x)*(1 - x^11)/(1 - 17*x + 152*x^11 - 136*x^12). (End)
