Index entries for linear recurrences with constant coefficients, signature (0, 0, 0, 0, 0, 0, 0, 568176, 0, 0, 0, 0, 0, 0, 0, -1).
FORMULA
G.f.: -(x^14 -2*x^13 +3*x^12 -17*x^11 +530*x^10 -2667*x^9 +3197*x^8 -9061*x^7 -3197*x^6 -2667*x^5 -530*x^4 -17*x^3 -3*x^2 -2*x -1) / (x^16 -568176*x^8 +1). - Colin Barker, Dec 25 2013
