Paderborn University reported on 10 Sep 2026 that all 25,000 groups had been solved by July and that Jürgen Klüners (Paderborn) and Gunter Malle (RPTU Kaiserslautern) won, finding more than 143,000 relevant polynomials "without using AI", while almost all other participants used it. The final status is from the university's press release; the organizers' own summary was not read. ## Key facts - Announcement: Terence Tao's blog, 16 June 2026, 'Third SAIR competition: inverse Galois challenge'; organizers John Jones, Jen Paulhus, David Roe, Andrew Sutherland and Tao (per search summaries of the post); verification by Magma and PARI/GP rather than Lean - Scope: 25,000 groups and 165,836 signatures; at the start the LMFDB held concrete polynomials for only 286 groups and 622 signatures (Paderborn) - Outcome: 'By July, all 25,000 groups had been solved', so the degree-24 inverse Galois problem was fully resolved for these groups; participants submitted millions of integer polynomials (Paderborn) - Winners: Jürgen Klüners (Paderborn) and Gunter Malle (RPTU Kaiserslautern), more than 143,000 relevant polynomials - AI: 'Almost all the other participants relied on the technology. Nevertheless, the team from Paderborn and Kaiserslautern managed to win the competition without using AI'; they used AI only to help write submission scripts (Paderborn) - Context: Tao's 9 Oct Math 2.0 lecture cites IGP24 as an example of new experimental mathematics ## What happened In June 2026 Terence Tao announced the third SAIR Foundation competition, run with the L-functions and Modular Forms Database (LMFDB): find explicit polynomials whose Galois groups are each of the transitive permutation groups of degree 24, almost the first open degree. Submissions were verified by computer algebra (Magma, PARI/GP). Paderborn University's press release of 10 Sep 2026 says the problem was finished: "By July, all 25,000 groups had been solved", from a starting point of polynomials for only 286 groups in the LMFDB. Jürgen Klüners and Gunter Malle won with more than 143,000 relevant polynomials. The release frames it as humans against AI: "Almost all the other participants relied on the technology. Nevertheless, the team from Paderborn and Kaiserslautern managed to win the competition without using AI." They used AI only for scripts that eased submission. The organizers' final report and the competition leaderboard were not read for this entry, so the 'all solved' claim rests on the university release. ## Why it matters IGP24 is one of the large crowdsourced experiments Tao has promoted as a new way to do mathematics with AI in the loop. Its result is a useful counterpoint to the many AI-credited results of autumn 2026: in a computational search problem, deep human expertise in Galois theory beat AI-assisted teams. ## Your AI and this story - GPT-6 Astra (training cutoff April 2026): 133 days after its cutoff - Claude Opus 5.5 (training cutoff June 2026): 72 days after its cutoff - Gemini 4 Argon (training cutoff March 2026): 163 days after its cutoff - Grok 4.7 (training cutoff May 2026): 102 days after its cutoff ## Sources 1.
