FORMULA
From Chai Wah Wu, Apr 22 2024: (Start)
a(n) = a(n-5) - a(n-10) + a(n-15) - a(n-20) + a(n-25) for n > 24.
G.f.: x^2*(-3*x^22 - x^21 - 2*x^20 - 2*x^19 - 5*x^17 + x^16 - 2*x^15 - 3*x^14 - 3*x^13 - 3*x^12 - 3*x^11 - 3*x^10 - 3*x^9 - 3*x^8 - 2*x^6 - x^5 - x^4 - 3*x^3 - 8*x^2 - 3*x - 1)/(x^25 - x^20 + x^15 - x^10 + x^5 - 1). (End)
