### A String of Pearls: Proofs of Fermat's Little Theorem

#### Abstract

What is elegant in prose turns out to be long-winded mechanically, and so we examine the effect of explicitly appealing to group theory. This has pleasant consequences both for the necklace proof, and also for some of the direct number-theoretic approaches.
