FORMULA
From Chai Wah Wu, Mar 07 2021: (Start)
a(n) = a(n-1) - a(n-30) + a(n-31) for n > 34.
G.f.: x^2*(-5*x^32 - 2*x^31 - x^30 + 2*x^29 - 2*x^28 + x^27 + 5*x^26 - x^25 + 3*x^24 - 8*x^23 + 7*x^22 - 8*x^21 + 5*x^20 + 4*x^19 - 7*x^18 + 4*x^16 - 4*x^15 + 2*x^14 - x^12 + 6*x^11 - 6*x^10 + 3*x^9 - 5*x^8 - x^7 + 9*x^6 - 4*x^5 - x^4 - 2*x^3 - 2*x^2 + x - 1)/(x^31 - x^30 + x - 1). (End)
