What it changes
If this solution held, problem #1190, a number theory question about covering systems, would be solved. The wiki presents it as a candidate full solution, not as a partial result.
What remains unclear
The wiki marks this contribution “not verified” (the legend of its flag) and the sources read name no verifier. It has been frozen since June 30, 2026, so a later development would not appear in it. The October 12, 2026 record from erdosproblems.com gives “Lean” (a language in which a computer checks every step of a proof) as the formal status of the problem; the sources read do not say whether this concerns this contribution.

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(d), “AI collaborating with humans” (significant human involvement). Humans named by the wiki: Przemek Chojecki; AI system: GPT-5.5 Pro. Date given by the wiki: April 30, 2026. Exact text: “Candidate full solution”; white flag (“unverified”, 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): resolved other than by a yes-or-no answer (informal_status=solved); 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/1190. DiscoverIA status: not evaluated (only the wiki's classification exists). Recorded on October 12, 2026.
