There are many operations that act on representations of a group, such as Sym^n, Wedge^n, and more exotic beasts. We can express these in terms of a simple, elegant set of operations, that involves, surprisingly, elementary number theory! I will explain how this works, prove some fun theorems about it, and, hopefully, answer the best generals question of all time.
