Abstract: Let $G$ be a finite group and $b(G)$ the largest irreducible character degree of $G$. In this note, we show the following results: if $b(G)<p^2$, then $\vert G:O_p(G)\vert _p\leq p$ ; if $b(G)<p^m$ and, in addition, $G$ is $p$-solvable with abelian Sylow $p$-subgroup, then $ \vert G:O_p(G)\vert _p< p^m$.
