Index entries for linear recurrences with constant coefficients, signature (0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 60470, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1).
FORMULA
G.f.: -(x^20 -5*x^19 +6*x^18 -11*x^17 +17*x^16 -28*x^15 +45*x^14 -73*x^13 +118*x^12 -191*x^11 +1073*x^10 +191*x^9 +118*x^8 +73*x^7 +45*x^6 +28*x^5 +17*x^4 +11*x^3 +6*x^2 +5*x +1) / (x^22 +60470*x^11 -1). - Colin Barker, Dec 17 2013
