• A triangle sequence of polynomial coefficients: p(x,n)=(x - 1)^(3*n + 1)*Sum[(k*(k + 1)*(2*k + 1)/6)^n*x^k, {k, 0, Infinity}]/x.at n=29A154284
• Irregular triangle T(n, k) = [x^k]( p(n, x) ), where p(n, x) = (1/x)*(1-x)^(3*n+1)*Sum_{k >= 0} (k*(k+1)*(2*k+1)/6)^n*x^k and p(0, x) = 1, read by rows.at n=30A174264
