The kernel of the action is the set of elements in that act as the identity on every element of . If the kernel is just , the action is faithful . Section 4.2: Groups Acting on Themselves Compute the orbits of the induced action on

Quizlet offers verified explanations for specific sections, including Groups Acting on Themselves by Conjugation (Section 4.3) and Sylow's Theorem (Section 4.5).

and prove the . Sylow's theorems use group actions to guarantee the existence of subgroups of prime power order (
