Abstract
The discriminant of a polynomial of the form has the form when are relatively prime. We investigate when these discriminants have prime power divisors. We explain several symmetries that appear in the classification of these values of . We prove that there are infinitely many pairs of integers for which this discriminant has no prime cube divisors. This result is extended to show that for infinitely many fixed , there are infinitely many for which the discriminant has no prime cube divisor.
