conjugate classes的用法和樣例：
例句
- Every group can be partitioned into equivalence classes called conjugacy classes.
所有群都可以劃分成叫做共軛類的等價類。 - And if we apply the same property to the identity automorphism, we get the closedness theorem for conjugacy classes of finite order in Lie groups.
而把同樣的性質應用到恆同自同構，我們會得到李群中有限階共軛類的閉性定理。
