 Why the word combinations? 2004-05-05 Megan pose la question :Why are locker combinations called locker combinations not locker permutations. The order of the numbers matter so why aren't they called locker permutations.Claude Tardif and Penny Nom lui répond. Combination locks 2002-08-17 John pose la question :How many combinations of three number codes can occur with a standard combination lock? The range of possible numbers is 0-39 which allows 40 different possible choices each turn of the dial. Each combination requires exactly three numbers (i.e. three turns of the dial). E.g. 35-40-5. Allow for reuse of the same number three times e.g.10-10-10. I don't think there is any preference shown for certain number combinations. Can you explain how the total is derived? Someone at the YMCA this week put this question to me and I gave an answer but I am not sure I am right--so I have come to you.Penny Nom lui répond.
