Vincenzo Librandi, Table of n, a(n) for n = 0..200
Index entries for linear recurrences with constant coefficients, signature (0,0,0,0,0,0,0,9602,0,0,0,0,0,0,0,-1).
FORMULA
G.f.: -(x^14 -x^13 +2*x^12 -5*x^11 +47*x^10 -99*x^9 +146*x^8 -245*x^7 -146*x^6 -99*x^5 -47*x^4 -5*x^3 -2*x^2 -x -1) / ((x^4 -4*x^3 +8*x^2 +4*x +1)*(x^4 -10*x^2 +1)*(x^4 +10*x^2 +1)*(x^4 +4*x^3 +8*x^2 -4*x +1)). - Colin Barker, Nov 22 2013
a(n) = 9602*a(n-8) - a(n-16) for n>15. - Vincenzo Librandi, Dec 23 2013
