  For an odd prime $p$, we consider free actions of $(\mathbb{Z}/p)^2$ on
$S^{2n-1}\times S^{2n-1}$ given by linear actions of $(\mathbb{Z}/p)^2$ on
$\mathbb{R}^{4n}$. Simple examples include a lens space cross a lens space, but
$k$-invariant calculations show that other quotients exist. Using the tools of
Postnikov towers and surgery theory, the quotients are classified up to
homotopy by the $k$-invariants and up to homeomorphism by the Pontrjagin
classes. We will present these results and demonstrate how to calculate the
$k$-invariants and the Pontrjagin classes from the rotation numbers.
