• Expansion of 1/sqrt((1-x)^2-8x^3).at n=16A098480
• Triangle, read by rows, where row n forms a polynomial in y=2*k that generates diagonal n as k=0,1,2,... for n>=0; thus T(n,k) = Sum_{j=0..n-k} T(n-k,j)*(2*k)^j, with T(n,0)=T(n,n)=1.at n=47A113711
• Column 2 of triangle A113711, in which row n forms a polynomial in y=2*k that generates diagonal n as k=0,1,2,... for n>=0.at n=7A113713
