FORMULA
From Chai Wah Wu, Apr 26 2024: (Start)
a(n) = a(n-1) - a(n-23) + a(n-24) for n > 24.
G.f.: x*(-5*x^23 - 3*x^22 + 8*x^21 - 8*x^20 + 2*x^19 + 2*x^18 - 3*x^16 + 2*x^15 - 4*x^14 + 4*x^13 - x^12 - x^11 + 5*x^10 + x^9 - x^8 + 2*x^7 - 7*x^6 + 6*x^5 - 5*x^4 + 3*x^3 - 6*x^2 + x - 1)/(x^24 - x^23 + x - 1). (End)
