FORMULA
Conjectures from Chai Wah Wu, May 05 2024: (Start)
a(n) = a(n-2) + 256*a(n-8) - 256*a(n-10) for n > 17.
G.f.: (32*x^17 - 256*x^15 + 96*x^14 - 172*x^13 - 152*x^12 + 124*x^11 + 40*x^10 - 124*x^9 + 24*x^8 + 199*x^7 + 82*x^6 + 41*x^5 + 18*x^4 + 12*x^3 + 5*x^2 + 3*x + 1)/(256*x^10 - 256*x^8 - x^2 + 1). (End)
