We’ve seen symmetric groups before. The symmetric group on an arbitrary set, or , is the group of bijections from the set to itself. As usual, we’re only interested in the finite case , which we call the symmetric group on symbols. These are pretty important finite groups, and so I hope you’ll accept my apology for writing a post just about their internal structure. The language we use to talk about symmetric groups ends up popping up all the time.
