AbstractLet P be a ranked partially ordered set. An h-family is a subset of P such that no h + 1 elements of the family lie on any single chain. P has the strong h-family property, if each maximal h-family in P is the union of h complete levels. Sufficient conditions for the strong h-family property are given
