Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing.

COMMENTS

The row polynomials p(n,x) (rising powers of x) appear as numerators of the column g.f.s of triangle A060058.

First column (m=0) gives A000364 (Euler numbers). See A091742, A091743, A091744 for columns m=1..3.

The main diagonal gives A001818. The row sums give A052502. The alternating row sums give A091745.

FORMULA

The row polynomials p(n, x) := Sum_{m=0..n} a(n, m)*x^m satisfy the differential equation: p(n, x) = x*((1-x)^2)*(d^2/dx^2)p(n-1, x) + (1+6*(n-1)*x+(5-6*n)*x^2)*(d/dx)p(n-1, x) + (3*n-2)*(1+(3*n-2)*x)*p(n-1, x), n >= 1, with input p(0, x)=1. - Wolfdieter Lang, Feb 13 2004
