  • groups of permutations
  • that every permutation can be written as either an even or odd number of transpositions, but not both
  • we did NOT learn that every group is isomorphic to a group of permutations (so sad no cure!)
  • that every permutation can be written as a product of disjoint closed loops, and that the order of a permutation is the least common multiple of the lengths of these closed loops
