Abstract:
We discuss some different combinatorial ways in which two classes of permutations might resemble each other. We'll focus on parallels between involutions in the symmetric group and the symmetric group as a whole, in particular parallels related to pattern avoidance. We'll also suggest some related interesting questions.
