%N Triangle read by rows: coefficients of a Hermite-like set of recursive polynomials that appear by integration to be orthogonal using the substitution on the Hermite recursion of n->f(n) where f(n)=A000045[n] is the Fibonacci sequence.
%C Note that Table[Integrate[Exp[ -x^2/2]*P[x,n]*P[x, n + 1], {x, -Infinity, Infinity}], {n, 0, 10}]; gives {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, ...}.
%C The row sums are: {1, 1, 0, -2, -2, 8, 24, -80, -584, 2136, 34256, ...}
%C Table[Apply[Plus, CoefficientList[P[x, n], x]], {n, 0, 10}];
