What it changes
If it held, this solution would be complete for Erdős problem #152, filed in the sources read under Sidon sets (the notion described above). The wiki, however, places it alongside comparable literature, Erdős, Sárközy, and Sós (1994), which it rates as similar. On October 12, 2026, erdosproblems.com listed it as “proved”.
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 is recorded. The sources read do not say to what extent the solution overlaps with that literature, nor what the “proved” state on erdosproblems.com rests on.

this status is an unofficial crowdsourced classification of the problem
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(b), “AI alongside literature” (AI in parallel with the literature (a comparable result found afterwards); no significant human involvement). Humans named by the wiki: none; AI system: DeepMind prover agent. Date given by the wiki: April 3, 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. Comparable literature found afterwards: Erdős, Sárközy, and Sós (1994), on April 3, 2026; similar according to the wiki: “Yes”. 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/152. 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.
