Cyclic group ($C_n$, C sub n)

A cyclic group is a type of group in which every element can be expressed as a power (or multiple) of a single element, known as a generator. In more formal terms, a group \( G \) is called cyclic if there exists an element \( g \in G \) such that every element \( a \in G \) can be written as \( g^n \) for some integer \( n \).
