Grokking the MATHAI puzzle

I haven’t posted here in a while bc of extreme work/research schedule. Decided to notify that I’m still alive :smiley:
So, I just wanted to say: seems that I’ve grokked the MATHAI puzzle which was included in the paper (link below). Just for fun…

The operation in question is: x + y (mod 97)
Or, in Python: (x + y) % 97

[Edit] Ok, this works only for latin alphabet, so something is missing… It would be really great to get the table in character format, not the PNG image. That would alleviate the daunting OCR task.

Yeah, also read the paper – the concept of grokking is very interesting and useful in some scenarios.
Hopefully I can post some software updates soon. Peace!
