FORMULA
G.f.: (x^4 -x^3 +x^2 -x +1)*(x^4 -x^2 +1)*(x^6 -x^5 +x^4 -x^3 +x^2 -x +1)*(x^8 +1)/((x -1)^8*(x^2 +x +1)^2*(x^4 +x^3 +x^2 +x +1)*(x^6 +x^5 +x^4 +x^3 +x^2 +x +1)). [Colin Barker, Sep 23 2012]
PROG
(PARI) s=8; a(n)=polcoeff(prod(i=1, s, (1+x^i))/(prod(i=1, s, (1-x^i))+x*O(x^n)), n) for(n=0, 50, print1(a(n), ", "))
