Sylow theorems (Theorem)

Let $ G$ be a finite group whose order is divisible by the prime $ p$. Suppose $ p^m$ is the highest power of $ p$ which is a factor of $ \vert G\vert$ and set

$\displaystyle k = \frac{\vert G\vert}{p^m}.$
Then
  1. the group $ G$ contains at least one subgroup of order $ p^m$,
  2. any two subgroups of $ G$ of order $ p^m$ are conjugate, and
  3. the number of subgroups of $ G$ of order $ p^m$ is congruent to $ 1$ modulo $ p$ and is a factor of $ k$.
