The intuitive effect of the Minimality Constraint is often to sift 73 the sensible maximal M-relations from the silly ones. Consider, for instance, a domain consisting of the experiences Xo, ... , XIOOO, where Xi matches Xj just in case the difference between i and j is no more than 500. Since xo does not match XIOOO, any M-relation involves at least two equivalence classes.
