A notation used to describe curves. The fundamental principle of Clebsch-Aronhold notation states that if each of a number of forms be replaced by a power of a linear form in the same number of variables equal to the order of the given form, and if a sufficient number of equivalent symbols are introduced by the Aronhold process so that no actual coefficient appears except to the first degree, then every identical relation holding for the new specialized forms holds for the general ones.
