Generating set of a module minimal if no proper subset of the set generates the module. If "R" is a field, then it is the same thing as a basis. Unless the module is finitely-generated, there may exist no minimal generating set. The cardinality of a minimal generating set need not be an invariant of the module; Z is generated as a principal ideal by 1, but it is also generated by, say, a minimal generating set }. What is uniquely determined by a module is the infimum of the numbers of the generators of the module. Let "R" be a local ring with maximal
