 Conjugacy class

The conjugacy class of $x\in G$ is its orbit under the conjugation action:

In group theory, a **conjugacy class** is a fundamental concept that helps understand the structure of a group. Given a group \( G \) and an element \( g \in G \), the conjugacy class of \( g \) is the set of elements in \( G \) that can be obtained by conjugating \( g \) with each element of \( G \).
