To understand ≈ 30 s reading time, estimated

What it changes

The sources read file the problem under number theory and Ramsey theory. If the solution held, it would be solved in full.

What remains unclear

The wiki points to a proof in Lean (a language in which a computer checks every step of a proof) without naming a third-party verifier, and no independent verification has been found. The sources read do not say what the solution takes from earlier work or what it adds. On erdosproblems.com, the problem is listed as solved as of October 12, 2026, and the sources read do not say whether that state rests on it.

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(c), “AI building on literature” (literature known beforehand and not rediscovered afterwards; no significant human involvement). Humans named by the wiki: none; AI systems: Aristotle, GPT-5.5 Pro. Date given by the wiki: June 21, 2026. Exact text: “Full solution (Lean)”; green flag (“full resolution”, according to the wiki's legend). The wiki flags a Lean proof without naming a third-party checker. Prior literature cited by the wiki: Erdős and Galvin (1991). 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): resolved other than by a yes-or-no answer (informal_status=solved); no formalised solution known (formal_status=unformalized). This status concerns the problem, not this contribution. Problem page not read by DiscoverIA: https://www.erdosproblems.com/948. DiscoverIA status: not evaluated (only the wiki's classification exists). Recorded on October 12, 2026.

Limits

DiscoverIA has not checked this contribution itself. The claimant supplies a Lean proof; as of this date, DiscoverIA has found no independent verification of this proof or of the result.
