The Longest Proof in Math, Explained

On October 27, 2026, the startup Axiom announced that the Classification of Finite Simple Groups, the longest proof in mathematics (about 15,000 pages in more than 500 articles by about 100 mathematicians), now checks in the Lean proof assistant: swarms of dozens of AI agents worked for 24 days and wrote about 43.1 million lines of Lean, and on the way they found a broken step in one published route to the Unbalanced Group Theorem and built a new one. The ASI Pill builds group theory from scratch in 3D, from the symmetries of a square to the periodic table of symmetry and the Monster, then shows how the proof was built and how the machines checked it.

Disclosure: this video's script and 3D scenes were made with Anthropic's Claude, and Anthropic's own Lean proof of Fermat's Last Theorem is mentioned in it. The video is independent and not sponsored.


SYMMETRY: a square's eight moves, combining them (the order matters), the table that is the group, and the same group in different clothes; why groups run crystals, chemistry, physics and the encryption in your phone. THE ATOMS: simple groups as the atoms of symmetry, the Jordan-Holder theorem, the icosahedron's sixty turns, and Galois and the equation of degree five. THE MONSTER: the periodic table of finite simple groups, its eighteen infinite families and twenty six loners, Mathieu's groups and Voyager's Golay code, the Monster and monstrous moonshine. THE PROOF: fifteen thousand pages, Feit and Thompson's 255 pages, Gorenstein's plan, the quasithin gap, the aging experts and the second-generation proof. THE MACHINE: Lean, Axiom's agent swarm, 43.1 million lines, the errata, the broken step in the Unbalanced Group Theorem and its repair with Ronald Solomon's 1976 ideas, and what is checked and what is not. Then the curve of AI formalization and Solve Everything's era of proof.
