Index entries for linear recurrences with constant coefficients, signature (1, 1, 1, 1, 1, 1, 1, -1).
FORMULA
G.f.: (t^8 + 2*t^7 + 2*t^6 + 2*t^5 + 2*t^4 + 2*t^3 + 2*t^2 + 2*t + 1)/(t^8 - t^7 - t^6 - t^5 - t^4 - t^3 - t^2 - t + 1).
MATHEMATICA
With[{num=Total[2t^Range[7]]+t^8+1, den=Total[-t^Range[7]]+t^8+1}, CoefficientList[ Series[ num/den, {t, 0, 40}], t]] (* Harvey P. Dale, Aug 05 2011 *)
