trailThe maximum number of unit distances among n points in the plane is at most n^(1+o(1)).
The square grid is not asymptotically optimal for maximizing unit distances among n planar points.
For arbitrarily large n there exist n-point planar sets with more than n^(1.014) unit-distance pairs.
Number-field counterexample (OpenAI construction, Alon et al. write-up, Sawin's explicit form)· against
There exist infinite towers of number fields of bounded root discriminant in which a fixed rational prime splits completely.

Robust Minkowski-grid construction (Lee, Pohoata, Zhu)· against
There exist n-point planar sets where every subset has a distance repeated at least c|A|^2/n^(1-delta) times.
