Čunihin's theorem (Theorem)
Theorem 1 (Cunihin)   Let $G$ be a finite, $\pi$ -separable group, for some set $\pi$ of primes. Then

Remarks

  1. For $\pi=\{p\}$ , this essentially reduces to the Sylow theorems (with unnecessary hypotheses).
  2. If $G$ is solvable, it is $\pi$ -separable for all $\pi$ , so such subgroups exist for all $\pi$ . This result is often called Hall's theorem. There is another Hall's theorem, which is similar to this one, can be be found here.
