= Understanding the state of 3x3 matrix multiplication
After yet another awesome announcement by <DeepMind> that it had improved theoretical 4x4 matrix multiplication reducing the number of scalar multiplications with its <AlphaEvolve> system, I decided to have a look at the smallest open size 3x3 to understand what was going on in there.
I've dumped what I gathered at:
