Claim. The conjectured asymptotic of Problem 1131,
is false. Liam Price posted the claim in the site's discussion thread on 26 April 2026, writing that GPT-5.5 Pro claims a disproof of the asymptotic the problem displays, with a link to a write-up on an online editor. The read link exposes only the editor's shell and no document to a reader without an account, so the corpus records the target of the claim from the thread post: the displayed asymptotic is the only asymptotic the problem states, and a disproof of it says that does not tend to . Price is the claimant, with the system named as the post names it.
Submission note. Posted to the site's forum by Liam Price on 26 April 2026:
GPT-5.5 Pro claims a disproof of the claimed asymptotic here.
Covers. The second question of Problem 1131, whether : the answer claimed is no. The first question, the minimal value of , is not determined. The bounds of Erdős, Szabados, Varma and Vértesi, which the site's commentary records, are consistent with either answer; Brutman and Toledano's numerical study (Comput. Math. Appl. 34 (1997), no. 12, 37--47) had pointed to a limit of near , as the problem page records.
Depends on. No page of this wiki.
Acceptance. None recorded. Nat Sothanaphan replied in the thread on
27 April 2026 that a standard check found no issues, and noted that the
Brutman--Toledano paper had earlier given numerical evidence against the
asymptotic; Sothanaphan is not the site's curator, so the reply is recorded here
and not listed as reviewed evidence. The site labels the problem OPEN (page
last edited 2026-01-23) and no journal publication, referee report or Lean
proof of the result is recorded, so no evidence is listed and the claim is
pending.
