N2 - The number of different sets that can be generated from a given set by applications of complement and closure operators is finite and small (e.g., 14). This fact, stated originally in [4] for topological closures, and the later in [2] for transitive closures of binary relations, is generalized to other closure operators, and several examples are given.
