Because of error functions in the result where constants should be

this is a difficult calculation.

Probably the wrong approach, but it is my best effort at getting

Gaussian normal type functions to give integers. There has got to be a better way than this:

maybe a conformal transform of the known Chebyshev Integration polynomials?

No recurrence formula was found for these polynomial, so they are probably wrong.

Row sums are:

P(x, n) = x*P(x, n - 1) - n*P(x, n - 2); L(x,n)=Integrate[Exp[y^2/4]*p(y,n-1),{y,-Infinity,x}]/(-2*Exp[ -x^2/4]) Here the weight function is taken as the square root of the Hermite weight function Exp[ -x^2/2] and then divided out of the end result.
