Abstract
This paper extends Bhargava's theory of -orderings of subsets of a Dedekind ring valid for prime ideals in . Bhargava's theory defines for integers invariants of , the generalized factorials , which are ideals of . This paper defines -orderings of subsets of a Dedekind domain for all nontrivial proper ideals of . It defines generalized integers , as ideals of , which depend on and on a subset of the proper ideals of . It defines generalized factorials and generalized binomial coefficients, as ideals of . The extension to all ideals applies to Bhargava's enhanced notions of -removed -orderings, and -orderings of order .
