FORMULA

From Chai Wah Wu, Sep 05 2016: (Start)

a(n) = a(n-1) - a(n-33) + a(n-34) for n > 33.

G.f.: x^2*(-9*x^31 + 4*x^30 + 5*x^28 - x^27 - 2*x^26 + 3*x^25 - 5*x^24 - 4*x^23 + 2*x^22 + 5*x^21 - 3*x^20 + 4*x^18 - 4*x^17 - 2*x^16 - 2*x^15 + 6*x^14 - 3*x^13 - x^12 + 2*x^10 - 2*x^9 - x^8 - x^7 + 8*x^6 - 7*x^5 + x^2 + 4*x - 6)/(x^34 - x^33 + x - 1). (End)
