When I was preparing the problems I used to test the 80 LLMs at the end of January I made a mistake. An LLM showed me where I was wrong.

I was wrong and the AI corrected me

It turns out that I made a mistake in this year's puzzles I asked AIs to solve. It was an AI that showed me the mistake, and I will fix this in this post
