This site is supported by donations to The OEIS Foundation.

 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. Other ways to donate

 OFFSET 0,2 COMMENTS A193962 is obtained by reversing the rows of the triangle A193961. LINKS FORMULA Write w(n,k) for the triangle at A193961.  The triangle at A193962 is then given by w(n,n-k). EXAMPLE First six rows: 1 4......1 40.....17....4 184....98....40....9 584....354...184...73...16 1484...979...584...298..116..25 MATHEMATICA z = 12; p[n_, x_] := Sum[((k + 1)^2)*x^(n - k), {k, 0, n}] q[n_, x_] := p[n, x] t[n_, k_] := Coefficient[p[n, x], x^k]; t[n_, 0] := p[n, x] /. x -> 0; w[n_, x_] := Sum[t[n, k]*q[n + 1 - k, x], {k, 0, n}]; w[-1, x_] := 1 g[n_] := CoefficientList[w[n, x], {x}] TableForm[Table[Reverse[g[n]], {n, -1, z}]] Flatten[Table[Reverse[g[n]], {n, -1, z}]]  (* A193961 *) TableForm[Table[g[n], {n, -1, z}]] Flatten[Table[g[n], {n, -1, z}]]  (* A193962 *) CROSSREFS Cf.
