%N A027858 Triangle of "Harmonic Coefficients" T(j,k), read by rows: (sum:n=1 to 
               j: T(j,n)*k^n)*k!/((j+k)!*j!) =(sum:n=1 to k:(1/n-1/(n+j)) =j*(sum:n=1

%F A027858 T(j, n)=j!*(sum:m=1 to n: S(j+1, n+1-m)*(-1)^(m+1)*(sum:i=1 to j:i^(-m-1))), 
               where S(M, N) is a Stirling number of first kind (unsigned). Also 
               T(j, n)=j!*(S(j+1, n+1)*(1+1/2+1/3+...1/j)-S(j+1, n+2)*(n+1)).
