Loren, Try the following: <<DiscreteMath`Permutations`\ n = 20; RandomPermutation[20] I think this does what you want.

I typically prepare questions for the exam in a sequential order starting at the beginning of the material and going to the end. I may have something like 20 short-answer questions. I want a program that will randomize the order of the questions. In other words, I want to provide n, the number of questions, and have the program provide a list of length n that contains all the numbers from 1 to n in a random order without any number being repeated or omitted. I'm sure that this is an easy task for Mathematica, but I can't figure out the best way to do it. Loren Dill
