  In 1993, Kahn and Kalai famously constructed a sequence of finite sets in
$d$-dimensional Euclidean spaces that cannot be partitioned into less than
$(1.203\ldots+o(1))^{\sqrt{d}}$ parts of smaller diameter. Their method works
not only for the Euclidean, but for all $\ell_p$-spaces as well. In this short
note, we observe that the larger the value of $p$, the stronger this
construction becomes.
