11-Square Packing Optimality Formalized in Lean with Help from Claude
ctjlewis · x · 2026-10-07
Manasseh announced that the optimality of packing 11 squares has been formalized in Lean, with Astra and Claude assisting the process, crediting collaborators including @ojoshe, @kleddamag, and @guzhou0806. A quote-tweet notes the author once helped the poster through Galois theory and abstract algebra in college, calling the work impressive. The result is another example of LLMs contributing to rigorous formal mathematics, not just proof search but full Lean formalization.
