Claude Solves Long-Standing Hadamard Order 668 Case and All Open Orders Under 2000

haider1 · x · 2026-08-12

A major breakthrough in mathematics has been achieved, as Claude successfully solved the long-standing Hadamard matrix problem of order 668.

According to researchers, this breakthrough not only cracked this specific case but also resolved all other previously open admissible orders under 2000. However, it remains unclear whether the model can solve the full Hadamard conjecture.
