Goal.
I would like to tell you a bit about my favorite subfields of mathematics (in no particular order), highlighting key theorems, ideas or concepts and why I like them so much. This is a variation of “My favorite theorems” and I park the videos on that list as well.

This time.
What is...group-based cryptography? Or: Subfields of mathematics 25.

Nobody is perfect, and I might have said something silly. If there is any doubt, then please check the references.
