Vincenzo Librandi, Table of n, a(n) for n = 0..200
Index entries for linear recurrences with constant coefficients, signature (0, 0, 0, 0, 10236, 0, 0, 0, 0, 1).
FORMULA
G.f.: -(x^8 -3*x^7 +16*x^6 -83*x^5 +265*x^4 +83*x^3 +16*x^2 +3*x +1) / (x^10 +10236*x^5 -1). - Colin Barker, Nov 22 2013
a(n) = 10236*a(n-5) + a(n-10) for n>9. - Vincenzo Librandi, Dec 23 2013
