Appears in sequences

• A triangular sequence based on concepts of operations on existing sequences: in this case the H(x,n) ( A060821) traditional Hermite is differentiated twice : p(x,n)=-x^2*H''(x,n)+H(x,n).at n=57A137449
• The n-th differences of the row A141045(n,.).at n=6A141055
• Expansion of e.g.f. exp(x^3/(1+x)).at n=9A293121
