FORMULA
G.f.: (Sum_{k>0} x^(14*k)/(Product_{j=1..k} 1 - x^(5*j))^3)/(Product_{j>=0} 1 - x^(5*j+1)). - Andrew Howroyd, Sep 16 2019
PROG
(PARI) seq(n)={Vec(sum(k=1, n\14, x^(14*k)/prod(j=1, k, 1 - x^(5*j) + O(x*x^(n-14*k)))^4)/prod(j=0, n\5, 1 - x^(5*j+1) + O(x*x^n)), -(n+1))} \\ Andrew Howroyd, Sep 16 2019
