Abstract
Primitive prime divisors play an important role in group theory and number theory. We study a certain numbertheoretic quantity, called φ∗_{n}(q), which is closely related to the cyclotomic polynomial φ_{n} (x) and to primitive prime divisors of q^{n}  1. Our definition of φ∗_{n}(q) is novel, and we prove it is equivalent to the definition given by Hering. Given positive constants c and k, we provide an algorithm for determining all pairs (n; q) with φ∗_{n}(q) ≤ cn^{k}. This algorithm is used to extend (and correct) a result of Hering and is useful for classifying certain families of subgroups of finite linear groups.
