1. The problem statement, all variables and given/known data Hi, I have been MIA lately due to work, but I am back with questions, and eager to learn! I am self studying, and so I have inconsistencies in my learning which I hope to iron out. Suppose you are told that the permutation ( 1 2 3 4 5 6 7 8 9 3 1 2 X Y 7 8 9 6) In S9 the symmetric group, where the images of 5 and 4 have been lost, is an even permutation. What must the images of 5 and 4 be? 2. Relevant equations 3. The attempt at a solution I thought X should be 5, and Y should be 4, so that you have 6 transpositions or am I oversimplifying the logic here? Thank you.
