Abstract
A commutative noetherian local ring is Gorenstein if and only if every parameter ideal of is irreducible. Although irreducible parameter ideals may exist in non-Gorenstein rings, Marley, Rogers, and Sakurai show there exists an integer (depending on ) such that is Gorenstein if and only if there exists an irreducible parameter ideal contained in . We give upper bounds for that depend primarily on the existence of certain systems of parameters in low powers of the maximal ideal.
