Direct power of a group

Definition
Let $$G$$ be a group and $$n$$ be a natural number. The $$n^{th}$$ direct power of $$G$$, denoted $$G^n$$, is defined as the defining ingredient::external direct product of $$n$$ copies of $$G$$.

Particular cases

 * $$n = 1$$: We get $$G$$ itself.
 * $$n = 2$$: We get the square of $$G$$.
 * $$n = 3$$: We get the cube of $$G$$.
