A202749 Triangle of numerators of coefficients of the polynomial Q^(4)m(n)</span> defined by the recursion <span class="maths">Q^(4)_0(n)=1;</span> for <span class="maths">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).
