The problem

Let gd(n)g_d(n) be minimal such that every collection of gd(n)g_d(n) points in Rd\mathbb{R}^d determines at least nn many distinct distances. Estimate gd(n)g_d(n). In particular, does

lim⁡d→∞gd(n)dn−1\lim_{d\to \infty}\frac{g_d(n)}{d^{n-1}}

exist?

Caveats

The wiki's classifications are provisional and are not a benchmark. Many Erdős problems have never had a thorough literature review, so a result that looks new may later turn out to be known; some problems were also stated ambiguously or incorrectly. See the problem page for the full discussion.
