%N A103361 Numerator of coefficient in the interpolation polynomial for initial 
               values of the factorial, read by rows.
%C A103361 Denominator N(n,n) of leading coefficient of the n-th polynomial = n-th 
               term of A053557. N(n,n)/D(n,n) = Sum{k=0..n}(-1)^k/k! = A000166/n! 
               = A053557/A053556, where D(n,n) is A103360.
%F A103361 N(n, k) in Sum{k=0..n}N(n, k)/D(n, k)*m^k=m!, m=0..n, with reduced fraction 
               N(n, k)/D(n, k) and D(n, k) is A103360. N(n, k)=a(n*(n+3)/2-k).
