%N Triangle read by rows: T(n,k) = n!*Pell(n-k+1)/k!, where Pell(n)=A000129(n).
%C The row polynomials form an Appell sequence (see Wikipedia). - _Tom Copeland_, Dec 03 2013.
%H Wikipedia, <a href="http://en.wikipedia.org/wiki/Appell_sequence">Appell sequence</a>
%F Column k has e.g.f. x^k/(k!*(1-2x-x^2)).
%F E.g.f. Sum T(n,k) x^n y^k / n! = e^{xy}/(1-2x-x^2). - Franklin T. Adams-Watters, Jan 12 2007
