β¦ Synopsis
We study subset families of a finite set that come from combinatorial decomposition theories such as graph substitution decomposition, boolean function decomposition, hypergraph or clutter substitution decomposition; see Omningham and Edmonds' paper [6].
We consider these families as ordered sets and we obtain characterization theorems in some particular cases. This gives us uniqueness decomposition results.

Suppose that any t members (t 2) of a regular family on an n element set have at least k common elements. It is proved that the largest member of the family has at least k 1Γt n 1&1Γt elements. The same holds for balanced families, which is a generalization of the regularity. The estimate is asympto
