Axiom Math says its AxiomProver system produced a machine-checked Lean formalization of the BGP246 theorem, a result concerning bounded gaps between primes, and released an open-source supporting library called PrimeGapsLib. The source says the formalization is conditional on the Bombieri-Vinogradov theorem and that the library depends on Mathlib and the PNT+ project. Axiom Math says it designed the components for reuse in future prime-gap work.
