Pretty awesome. I fed it to Astra Max and it took over 2 minutes ( https://chatgpt.com/share/6ab1bd98-7974-83e8-9734-8e10b5b3ef... ) so that's interesting in itself. If we knew how she did that, I wonder if the insight would be transferable to transformer-based ANNs.
Interesting character even aside from her mental-arithmetic abilities.
Edit: Deepseek 4.1 Flash running locally got it in 134 seconds. Beaten by Astra but not by much. Neither model seems to recognize the problem (at least it doesn't appear in DS4.1's chain of thought.)
I saw a video at one point about how she probably did it, but I can't find it. I feel it was Numberphile or Computerphile or StandUpMaths, something in that general circle.
