FORMULA

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

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

a(n) = 2*a(n-1) - a(n-2) - a(n-4) + 3*a(n-5) - 3*a(n-6) + a(n-7) + a(n-9) - 2*a(n-10) + a(n-11) for n>10.
