As far as I know, there is no proof that $\Delta_{n+1} \le \Delta_n$ for all sufficiently large $n$. Even if you know a good packing in $n$ dimensions, you might not get a good packing by tiling it in one higher dimension (although this strategy works well in low dimensions). See Conway and Sloane for a lot more. | |
