## Number theory notes

Back to work on this paper, I’m looking through an intro to number theory to find any helpful ideas.

Random notes

One notational convention I didn’t know was that if $\frac{a}{b}$ is an integer, then we write “b divides a” as $b|a$.  If this is not the case and “b does not divide a” then we write $b \dagger a$.  In the paper I’m working on I use the coprime notation of $a \bot b$.

Fermat’s little theorem – if $p$ is prime then $p | n^p-n$

Wilson’s theorem – if $p$ is prime then $p|[(p-1)! + 1]$
