	A punch-code lock box		2010-11-29
		From Doug: I am a real estate agent that uses punch-code lock boxes on houses to store the keys. I need to crack the code on one of our boxes, so I need a list of the possible combinations. Rules: 4 digit code Numbers 0-9 Each number can only be used once Order of the numbers does not matter. With advice from this site, I have calculated that there should be 210 possibilities. 10x9x8x7 (5040) gives me the total number possibilities and 4x3x2x1 (24) gives me the total number of ways to arrange those numbers. So if I divide the possibilities by the arrangement, I get 210. (5040 / 24 = 210) GREAT!!! Now, how do I develop a list of those 210 combinations? Thanks for your help. Answered by Robert Dawson.
