FORMULA
Empirical: a(n) = a(n-1) +a(n-2) -a(n-5) -a(n-6) -a(n-7) +a(n-8) +a(n-9) +a(n-10) -a(n-13) -a(n-14) +a(n-15).
Empirical: G.f. -x*(15 +92*x +275*x^2 +573*x^3 +911*x^4 +1196*x^5 +1305*x^6 +1198*x^7 +913*x^8 +574*x^9 +275*x^10 +91*x^11 +13*x^12 +x^14) / ( (1+x+x^2) *(x^4+x^3+x^2+x+1) *(x^2+1) *(1+x)^2 *(x-1)^5 ). - R. J. Mathar, Dec 15 2011
