Formula

From Chai Wah Wu, Apr 22 2024: (Start)

a(n) = a(n-1) - a(n-22) + a(n-23) for n > 25.

G.f.: x^2*(-5*x^23 - 2*x^22 - x^21 - x^19 + x^18 + 8*x^17 - 8*x^16 + 6*x^15 - 3*x^14 - 2*x^13 - 2*x^11 + 2*x^10 + 6*x^9 - 5*x^8 + x^7 + 5*x^6 - 5*x^5 - 4*x^3 + 4*x^2 - 3*x - 1)/(x^23 - x^22 + x - 1). (End)
