- Please read your textbook, pages 204 through 209 (this covers permutations, transpositions, signs, inversions).
- Do Exercise 3, but compute the sign 3 different ways (we will start with this example in class Wed):
- First, by drawing the cycle diagram and using cycle lengths
- Second, by decomposing it into transpositions and counting those
- Third, by counting the total number of inversions
