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, 0, 0, 4702, 0, 0, 0, 0, 0, 0, 0, -1).
FORMULA
G.f.: -(x^2-x-1)*(x^4+5*x^2+1)*(x^8+28*x^4+1) / (x^16-4702*x^8+1). - Colin Barker, Nov 18 2013
a(n) = 4702*a(n-8) - a(n-16) for n>15. - Vincenzo Librandi, Dec 19 2013
