Vincenzo Librandi, Table of n, a(n) for n = 0..200
Index entries for linear recurrences with constant coefficients, signature (0, 0, 0, 0, 0, 8980, 0, 0, 0, 0, 0, -1).
FORMULA
G.f.: -(x^11 -22*x^10 +45*x^9 -67*x^8 +1452*x^7 -1519*x^6 -4490*x^5 -1519*x^4 -1452*x^3 -67*x^2 -45*x -22) / (x^12 -8980*x^6 +1). - Colin Barker, Nov 28 2013
a(n) = 8980*a(n-6)-a(n-12). - Wesley Ivan Hurt, May 27 2021
