What it changes

If this result held, it would advance this number theory problem without solving it entirely.

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; the sources read record no independent verification. It files the contribution under category 1(a) (AI standalone; comparable literature unknown; no significant human involvement) and marks it 🟡 “partial progress” (wiki legend).

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(a), “AI standalone” (AI alone; no comparable literature known; no significant human involvement). Humans named by the wiki: none; AI systems: Codex, GPT-5.5, ProofCouncil. Date given by the wiki: June 10, 2026. Exact text: “Partial result (Lean)”; yellow flag (“partial progress”, 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): open (informal_status=open); 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/539. 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.
