Some authors include an additional axiom referred to as the closure under the operation " $\cdot$ ", which means that $a \cdot b$ is an element of $G$ for every $a$ and $b$ in $G$ . This condition is subsumed by requiring " $\cdot$ " to be a binary operation on $G$ . See Lang 2002. Lang, Serge (2002), Algebra, Graduate Texts in Mathematics, vol. 211 (Revised third ed.), New York: Springer-Verlag, ISBN 978-0-387-95385-4, MR 1878556

An example is group cohomology of a group which equals the singular cohomology of its classifying space, see Weibel 1994, §8.2. Weibel, Charles A. (1994), An introduction to homological algebra, Cambridge Studies in Advanced Mathematics, vol. 38, Cambridge University Press, ISBN 978-0-521-55987-4, MR 1269324, OCLC 36131259
Elements which do have multiplicative inverses are called units, see Lang 2002, p. 84, §II.1. Lang, Serge (2002), Algebra, Graduate Texts in Mathematics, vol. 211 (Revised third ed.), New York: Springer-Verlag, ISBN 978-0-387-95385-4, MR 1878556
For example, a finite subgroup of the multiplicative group of a field is necessarily cyclic. See Lang 2002, Theorem IV.1.9. The notions of torsion of a module and simple algebras are other instances of this principle.
