In this paper we'll discuss permutations (rearrangements of objects),
how to combine them, and how to construct complex permutations from
simpler ones. We'll talk a bit about groups of permutations as well.
Almost all the interesting examples in the paper are related to
solving the well-known ``Rubik's Cube'' puzzle. It is easiest to read
this paper if you have a Rubik's Cube with you (and a screwdriver
to take it apart if you don't know how to solve it).
