%N Triangle of numerators of coefficients of the polynomial Q^(4)_m(n) defined by the recursion Q^(4)_0(n)=1; for m>=1,Q^(4)_m(n)=sum{i=1,...,n}i^4*Q^(4)_(m-1)(i). For m>=0, the denominator for all 5*m+1 terms of the m-th row is A202369(m+1)
%C See comment in A175669.
%F Q^(4)_n(1)=1.
%e The sequence of polynomials begins
%e Q^(3)_0=1,
%e Q^(3)_1=(6*x^5+15*x^4+10*x^3-x)/30,
%e Q^(3)_2=(36*x^10+280*x^9+795*x^8+900*x^7+88*x^6-450*x^5-20*x^4+200*x^3+x^2-30*x)/1800.
