Claim. Two results from the anonymous note Two results on a distance multiplicity problem of Erdős, posted with its verification code in the GitHub repository mathematiclover1337/erdos-132-note at the revision linked above. First, the first question of Problem 132 holds for , , , and : every set of points in the plane determines two distinct distances each of which occurs between at most pairs. The proof is by the counting reduction and descent along the diameter graph, the cases and by enumerating the intersections of circles about the vertices of the regular heptagon and nonagon, and every step is checked by a single verification script. The note says these cases were found independently before the earlier postings in the thread were seen, and assigns priority for them to Marchetto's note of 5 July 2026 (claim page) and, for , to Zeraoulia's note of 28 January 2026 (claim page). Second, its main contribution: writing and for the second-largest and smallest distances of an -point set and for multiplicity, there are -point sets with , so the constant of Problem 1.6 of Clemen, Dumitrescu and Liu [CDL25] is at least , improving their ; the construction takes an even regular -gon with , places the points at distance from consecutive vertices under the edge midpoints of the antipodal arc so that each collects two minimum-distance pairs, and fills the rest with a triangular-lattice patch. The note conjectures that is optimal. The thread post also says that the thread's earlier GPT-5.2 argument for relies on a classification of eight-point four-distance sets that does not exist in the literature; Marchetto's note identifies that classification as Theorem 1.2(a) of Shinohara's 2008 paper, and the two notes agree that the case holds by descent.
Covers. The first question for , , , and , as an independent proof of cases first claimed on Marchetto's and Zeraoulia's pages; and the lower bound , which concerns a related extremal quantity and is not one of the problem's questions. Neither question of the problem is settled in general.
Depends on. No page of this wiki.
Claimant and postings. The note was posted on 25 July 2026 in the problem's discussion thread, not on its proof-claims tab, from the account ienjoymath; the note's author line reads Anonymous, so the forum account names the claimant here. The note and the repository's README say the results were obtained with substantial assistance from an AI system, Anthropic's Claude, and ask that the mathematics be judged on the proofs and the verification code. The repository's single-command script checks every claim of the note in exact arithmetic where applicable; none of it was run, and none of the proofs was checked, by this corpus. Jones's claim of 25 September 2026 (claim page) cites this bound as the lower bound against which its upper bound stands.
Acceptance. None documented. The note is not on arXiv and has no journal record, the site labels the problem OPEN and its page does not credit the result, and no outside review is known. The claim is therefore claimed.
