Consider the triangular lattice with minimal distance between two points $1$. Denote by $f(t)$ the number of distances from any points $\le t$. For example $f(1)=6$, $f(\sqrt{3})=12$, and $f(3)=18$.Let $x_1,\dots ,x_n\in {\mathbb{R}}^2$ be such that $d(x_i,x_j)\ge 1$ for all $i\ne j$. Is it true that, provided $n$ is sufficiently large depending on $t$, the number of distances $d(x_i,x_j)\le t$ is less than or equal to $f(t)$ with equality perhaps only for the triangular lattice?In particular, is it true that the number of distances $\le \sqrt{3}-ϵ$ is less than $1$?
