SEMIGROUP

Semigroup

In mathematics, a semigroup is an algebraic structure consisting of a set together with an associative binary operation. A semigroup generalizes a monoid in that a semigroup need not have an identity element. It also generalized a group to a type where every element did not have to have an inverse, thus the name semigroup.
