<abstract xml:lang="en">
We consider the problem of ranking sets of objects, the members of which are mutually compatible. Assuming that each object is either good or bad, we axiomatically characterize three cardinality-based rules which arise naturally in this dichotomous setting. They are what we call the symmetric di.erence rule, the lexicographic good-bad rule, and the lexicographic bad-good rule. Each of these rules induces a unique additive separable preference relation over the set of all groups of objects.
