In a group action,
\beginsolution4.3.1 Let $G$ be a finite group such that $|G| = p^a$ where $p$ is a prime number and $a \ge 1$. We utilize the class equation for $G$: \[ |G| = |Z(G)| + \sum_i=1^r [G : C_G(g_i)] \] where $g_1, g_2, \dots, g_r$ are representatives of the distinct conjugacy classes of $G$ not contained in the center $Z(G)$. By definition, if $g_i \notin Z(G)$, then $C_G(g_i)$ is a proper subgroup of $G$. By Lagrange's Theorem, the index $[G : C_G(g_i)]$ must divide $|G| = p^a$. Since it is strictly greater than 1, it must be a multiple of $p$. Thus, $p$ divides $[G : C_G(g_i)]$ for all $i$. Looking at the class equation modulo $p$: \[ 0 \equiv |Z(G)| + 0 \pmod p \implies |Z(G)| \equiv 0 \pmod p \] Since the identity element $e \in Z(G)$, we know $|Z(G)| \ge 1$. Because $|Z(G)|$ is a multiple of $p$, it must be that $|Z(G)| \ge p$. Therefore, $G$ possesses a non-trivial center. \endsolution Use code with caution.
