Group theory.

Something is incredibly beautiful to me about classifying the kinds of symmetry things can have.

I’m trying to understand where the sporadic simple groups come from. Starting with the Matthieu groups. So far it seems to be due to some anomaly in Pascal’s triangle, but I’m still trying to put it together. “Another Roof” on YouTube has a good video about this.

I'm over a decade out from my maths undergrad degree, but I still remember how beautiful Group Theory felt. Enjoy it!

i was interested in signal processing with group theory it was quite interesting to see how matrix multiplication corresponds to modulo over finite group.(I am not a math major).
