Formula

Conjectures from Chai Wah Wu, Dec 10 2018: (Start)
a(n) = a(n-1) - a(n-2) + a(n-3) - a(n-4) + a(n-5) + a(n-13) - a(n-14) + a(n-15) - a(n-16) + a(n-17) - a(n-18) for n > 18.
G.f.: (x^18 + 2*x^17 + 3*x^16 + 5*x^15 + 7*x^14 + 9*x^13 + 9*x^12 + 8*x^11 + 8*x^10 + 8*x^9 + 8*x^8 + 8*x^7 + 9*x^6 + 9*x^5 + 7*x^4 + 5*x^3 + 3*x^2 + 2*x + 1)/(x^18 - x^17 + x^16 - x^15 + x^14 - x^13 - x^5 + x^4 - x^3 + x^2 - x + 1). (End)
