COMMENTS
| The row polynomials pPL1(n,x) := sum(A062133(n,m)*x^m,m=0..n) and pPL2(n,x) := sum(a(n,m)*x^m,m=0..n) appear in the k-fold convolution of the associated Pell numbers PL(n) := A001333(n+1), n >= 0, as follows: PL(k; n) := A054458(n+k,k)= (2*pPL1(k,n)*PL(n+1)+pPL2(k,n)*PL(n)/(k!*8^k), k >= 0.

pPL1(1,n)=1+2*n; pL2(1,n)=2; PL(1; n)= A054459(n)=((1+2*n)*PL(n+1)+PL(n))/4.
