Minkowski-Hlawka Theorem

There exist lattices in $n$-D having Hypersphere Packing densities satisfying

\eta\geq{\zeta(n)\over 2^{n-1}},

where $\zeta(n)$ is the Riemann Zeta Function. However, the proof of this theorem is nonconstructive and it is still not known how to actually construct packings that are this dense.
