Abstract: Let $ G$ be a finite group of order divisible by a prime $ p$ acting on an $ \mathbb{F}$ vector space $ V,$ where $ \mathbb{F}$ is the field with $ p$ elements and $ \dim_{\mathbb{F}} V=n$. Consider the diagonal action of $ G$ on $ m$ copies of $ V.$ This note sharpens a lower bound for $ \beta(\mathbb{F}[\oplus_mV]^G)$ for groups which have an element of order $ p$ whose Jordan blocks have sizes at most 2.
