Numerators of sequence a[ 1, n ] in (a[ i, j ])^4 where a[ i, j ] = 1/i if j<=i, 0 if j>i
Numerators of (H(n, 1)^3+3*H(n, 1)*H(n, 2)+2*H(n, 3))/(6*n)= ((gamma+Psi(n+1))^3+3*(gamma+Psi(n+1))*(1/6*Pi^2-Psi(1, n+1))+2*Zeta(3)+Psi(2, n+1))/(6*n), where H(n, m) = Sum_{i=1..n} 1/i^m are generalized harmonic numbers. - Vladeta Jovovic (vladeta(AT)Eunet.yu), Aug 10 2002
