Let $e_3(n)$ be the minimum number of ordinary planes determined by $n$ points, and let $n_0$ be the threshold appearing in the source's theorem giving the exact values of $e_3(n)$…

Let $e_3(n)$ denote the minimum number of ordinary planes determined by a set of $n$ points in the relevant geometric setting. Lower-bound conjecture for $e_3(n)$. For all $n$, … T…
