What it changes
Problem #543 belongs to number theory and group theory. If the solution held, it would be dealt with in full. The wiki notes, however, an earlier comparable result, Erdős and Hall (1977), found afterwards, on January 26, 2026, and marked as similar (“Yes”).
What remains unclear
The sources read do not say what the solution consists of or whether anyone has checked it. A verification published after the wiki's freeze would not appear there.

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: GPT-5.2 Pro. Date given by the wiki: January 21, 2026. Exact text: “Full solution”; green flag (“full resolution”, according to the wiki's legend). Comparable literature found afterwards: Erdős and Hall (1977), on January 26, 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): disproved, answered in the negative (informal_status=disproved); 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/543. DiscoverIA status: not evaluated (only the wiki's classification exists). Recorded on October 12, 2026.
