What it changes

Problem #90 is a geometry question about distances. If the result held, it would give a better explicit bound, that is a limit written with its constants, and not only an order of magnitude.

What remains unclear

The wiki shows the green flag for full resolution next to a text that speaks of an improved bound; the sources read do not say what would be resolved, what the value of the bound is, or what it improves. They name no verifier. The wiki has been frozen since June 30, 2026, so a verification published since then would not appear there.

Method

Source: the “AI contributions to Erdős problems” wiki of the teorth/erdosproblems repository (a repository presented by Terence Tao in his blog post of August 31, 2025); frozen on June 30, 2026 (commit c8ad430, “freeze”) and read on October 12, 2026 in the git repository. Category 1(d), “AI collaborating with humans” (significant human involvement). Humans named by the wiki: Ingo Althöfer, Michael Emmerich, Paata Ivanisvili, Tomasz Kania, leloy, mlewko, Eric Naslund, norxornor, Will Sawin, Carl Schildkraut, spiderduckpig, Tseng; AI system: GPT-5.5 Pro. Dates given by the wiki: “21 May-9 Jun, 2026”. Exact text: “Improved explicit bound”; green flag (“full resolution”, according to the wiki's legend). Literature cited by the wiki: none. Status of the problem in the teorth/erdosproblems community database (data/problems.yaml, unofficial classification, snapshot of October 12, 2026 with no commit identified, current state, not that of June 2026): disproved, answered in the negative (informal_status=disproved); a solution has been formalised in Lean (formal_status=Lean). This status concerns the problem, not this contribution. Problem page not read by DiscoverIA: https://www.erdosproblems.com/90. DiscoverIA status: not evaluated (only the wiki's classification exists). Recorded on October 12, 2026.
