https://en.wikipedia.org/wiki/Module_(mathematics)Finitely generated An R-module M is finitely generated if there exist finitely many elements x1, ..., xn in M such that every element of M is a linear combination of those elements with coefficients from the ring R. Cyclic A module is called a cyclic module if it is generated by one element. Free A free R-module is a module that has a basis, or equivalently, one that is isomorphic to a direct sum of copies of the ring R. These are the modules that behave very much like vector spaces.
