►This lays the foundation for consideration of exceptional OP’s wherein a finite number of (possibly non-sequential) polynomial orders are missing, from what is a complete set even in their absence.

►Exceptional type I -EOP’s, form a complete orthonormal set with respect to a positive measure, but the lowest order polynomial in the set is of order
, or, said another way, the first polynomial orders, are missing.
