G. C. Greubel, Table of n, a(n) for n = 0..650
Index entries for linear recurrences with constant coefficients, signature (33, 33, 33, 33, -561).
FORMULA
G.f.: (t^5 + 2*t^4 + 2*t^3 + 2*t^2 + 2*t + 1)/(561*t^5 - 33*t^4 - 33*t^3 - 33*t^2 - 33*t + 1).
a(n) = 33*a(n-1)+33*a(n-2)+33*a(n-3)+33*a(n-4)-561*a(n-5). - Wesley Ivan Hurt, May 11 2021
