Definition:Generated Algebraic Substructure

Definition
Let $\struct {A, \circ}$ be an algebraic structure.

Let $G \subseteq A$ be any subset of $A$.

The algebraic substructure generated by $G$ is the smallest substructure of $\struct {A, \circ}$ which contains $G$.

It is written $\gen G$.

Also known as
Some sources refer to such a $G$ as a set of generators of $B$, but this terminology is misleading, as it can be interpreted to mean that each of the elements of $G$ is itself a generator of $\gen G$ independently of the other elements.
