Express as the product of disjoint cycles:
a. (1,2,3)(4,5)(1,6,7,8,9)(1,5)
b. (1,2)(1,2,3)(1,2)
I now how to do in 2 row permutations, with right to - left. can any one tell me , how to express it without transfer it into 2 row permutations.
One more question, How do we find out it's odd or even permutaions.
Thank you. I am doing my past exam paper, university doesn't give us answer.
