Table of n, a(n) for n=0..40.

Formula

Conjectures from Colin Barker, Feb 09 2018: (Start)

G.f.: (1 + x - x^3 - 4*x^4 - 4*x^5 - 9*x^6 - 5*x^7 - 3*x^8 - x^9 + x^10) / ((1 - x)^3*(1 + x)^2*(1 - x + x^2)*(1 + x + x^2)^2).

a(n) = a(n-2) + a(n-3) - a(n-5) + a(n-6) - a(n-8) - a(n-9) + a(n-11) for n>10.
