%F Conjectures from _Chai Wah Wu_, Apr 18 2024: (Start)
%F a(n) = a(n-1) - a(n-4) + a(n-5) - a(n-8) + a(n-9) - a(n-12) + a(n-13) + a(n-16) - a(n-17) + a(n-20) - a(n-21) + a(n-24) - a(n-25) + a(n-28) - a(n-29) for n > 28.
%F G.f.: x*(-x^27 + 2*x^26 - x^23 + 3*x^22 + 2*x^21 - x^20 + 2*x^19 + 5*x^18 + x^17 + 2*x^16 + 4*x^15 + 4*x^14 + 4*x^13 + 4*x^12 + 5*x^11 - 14*x^10 + 4*x^9 + 4*x^8 + 5*x^7 + x^6 + 2*x^5 + 5*x^4 + 2*x^3 - x^2 + 3*x + 2)/((x - 1)^2*(x + 1)*(x^2 + 1)*(x^4 + 1)^2*(x^8 + 1)^2). (End)
