MATA02 - Lecture 8d - Modular power patterns
Lecture 8d of MATA02: The Magic of Numbers
(https://courses.ywyu.net/MATA02-2022-...)
What patterns can you find in powers under modular arithmetic?
This lecture is slowly building up to Fermat's little theorem, which will be proved in the next lecture. (the lecture was rather more interactive than some, so fast forwarding through some of the student work time)
