Axiom auto-formalizes the Classification of Finite Simple Groups in Lean: history's largest proof, computer-verified

GuillaumeLample · x · 2026-10-28

Axiom announced a complete Lean auto-formalization of the Classification of Finite Simple Groups—the "periodic table of symmetry"—calling it the largest math proof in human history to be computer-verified.

The original proof spans roughly 15,000 pages built by over 100 mathematicians across generations. fcharton (retweeted by Guillaume Lample) praised it as useful mathematics that no realistic number of mathematicians could have achieved in reasonable time—a welcome change from the usual last-mile scooping.
