Question 862687: Prove a permutation of 4 letters does not have 40 distinct elements but a permutation of 5 letters has 50 distinct elements. Answer by richard1234(7193) (Show Source):
You can put this solution on YOUR website! A permutation of five letters or objects does not have 50 distinct "elements." I think what you meant to say is that "the set of permutations of 5 letters has 50 distinct elements" which is true since 5! = 120 >= 50, while 4! < 40.
