Those restricted classes are exactly "classical orthogonal polynomials".

Stronger results are known for restricted classes of polynomials or algebraic numbers.

These classes are now considered restricted classes, although previously they were referred to as one-designs.

These systems process restricted classes of information associated with these folk domains.

Ferret: Piranhas are not in this restricted class.
