The paper presents propagation rules that are common to the minimum constraint family and to the number of distinct values constraint family. One practical interest of the paper is to describe an implementation of the number of distinct values constraint. This is a quite common counting constraint that one encounters in many practical applications such as time tabling or frequency allocation problems.
