 OFFSET 1,13 LINKS FORMULA Replace term A003983(n,k) with F(n). Triangle T(n,k)=sum{j=0..n, [j<=k]*[j<=n-k]*(F(j+1)-F(j))}. [From Paul Barry, Jan 18 2009] EXAMPLE First few rows of A003983 are [1; 1,1; 1,2,1; 1,2,2,1;...] which become [F(1); F(1),F(1); F(1),F(2),F(1); F(1),F(2),F(2),F(1);...] = 1; 1, 1; 1, 1, 1; 1, 1, 1, 1; 1, 1, 2, 1, 1; 1, 1, 2, 2, 1, 1; 1, 1, 2, 3, 2, 1, 1; 1, 1, 2, 3, 3, 2, 1, 1; 1, 1, 2, 3, 5, 3, 2, 1, 1; 1, 1, 2, 3, 5, 5, 3, 2, 1, 1; 1, 1, 2, 3, 5, 8, 5, 3, 2, 1, 1; ...
