naval · x · 2026-07-30
User @monotau shared a breakthrough in advanced mathematics achieved by AI. After extensive back-and-forth, GPT-5.6 Sol successfully generated a proof for a Ramsey number inequality, which was then formally verified using Lean. As a consequence, this establishes a new lower bound: R(12,12) >= 1641.
