Loren Dill, Will the following work for your purposes? Needs["DiscreteMath`Combinatorica`"] NumbofQuestions = 20; Table[RandomPermutation[NumbofQuestions]] work for your purposes? John C. Erb -----Original Message----- From: Loren Dill [mailto:lorendill at mediaone.net] To: mathgroup at smc.vnet.net Subject: [mg28445] [mg28434] Rearrangement of a sequence into random order Hi, I'm a math teacher, and need to prepare exams from time to time. 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
