Abstract : In the report all of the closed sets of nvariable Boolean functions are obtained. The property of these sets is such that if the variables of any function of a closed set are replaced by variables from (x sub 1, x sub 2, ..., x sub n) or by functions of the set, then the function obtained also belongs to the set. Also obtained is a set of nonredundant generators for each closed set. These generators define in essence a collection of building blocks from which networks can be constructed to realize any function from the closed set. (Author)
