Abstract: Let $ p$ be a prime and $ G$ a finite group, not of type $ {L_2}(p)$, with a cyclic Sylow $ p$-subgroup $ P$. Assume that $ G = G'$. The purpose of this note is to put some rather stringent lower bounds on the degree $ d$ of a faithful indecomposable representation of $ G$ over a field of characteristic $ p$ given certain conditions on the normalizer $ N$ and the centralizer $ C$ of $ P$ in $ G$. In particular, if the center of $ G$ has order 2 and $ \vert N:C\vert = p - 1$, then $ d \geqq p - 1$.
