##### Abstract

A classical conjecture in transformation group theory states that if $G={\left(ℤ∕p\right)}^{r}$ acts freely on a product of $k$ spheres ${S}^{{n}_{1}}×\cdots ×{S}^{{n}_{k}}$, then $r\le k$. We prove this conjecture in the case where the dimensions $\left\{{n}_{i}\right\}$ are high compared to all the differences $|{n}_{i}-{n}_{j}|$ between the dimensions.
