A combination lock 2005-10-03 A bicycle owner pose la question :What are the number of permutations (Combinations?) of a combination lock of a cylinder with four separate movable rings.

The combinatiion for a keybox 2004-05-17 Darrin pose la question :I have a puzzle question based on reality. I have a real-estate type keybox (Supra) that has 10 digits, 0-9. I am trying to figure out a methodical way to test all number combinations to it to open it. (totally legal- it was taken from the trash at a jobsite since they couldn't open it!) The combination could be any or all of the digits, but any digit is only used once. This is not like a simplex lock problem where a combination of keypresses would be different- i.e. 1,2,3 is the same as 1+2,3. Any ideas?Penny Nom lui répond. 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.
