What it changes

Problem #347 belongs to number theory and complete sequences. If the solution held, the problem would be solved; the wiki marks the entry as a full resolution.

What remains unclear

The wiki points to a Lean proof (a language in which a computer checks every step of a proof) without naming a third-party verifier, and no independent verification is on record. The sources read do not say what each human or each model contributed.

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: Enrique Barschkis, Wouter van Doorn, jbbaehr22, Bartosz Naskrecki, Terence Tao; AI systems: Aristotle, Claude Opus, Codex, GPT. Terence Tao, named here as a contributor, also presented the repository in his blog post of August 31, 2025. Dates given by the wiki: “25 Oct, 2025-4 Feb, 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. 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): proved, answered in the affirmative (informal_status=proved); 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/347. 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.
