I looked but could not find any methods that they were talking about. I would like to see what they used.

 Is there a 120 Chart for Combination Locks? Hmmm .....

  • If what you want are all possible three digit numbers then you have 10 choices for the first digit, you have 10 choices for the 2nd digit,and you have 10 choices for the 3rd digit giving you
  •  10x10x10 = 1000 in all.
  • If what you want are all possible three digit numbers with no repetition of the digits then you have 10 choices for the first digit, you have 9 choices for the 2nd digit, and you have 8 choices for the 3rd digit giving you
  • 10x9x8 = 720 in all.
  • If what you actually want is  - combinations - that's something quite different. It is the number of ways to choose 3 of the 10 digits in which order is not important. There are 6 = 3x2x1 ways to order 3 digits in a row.  the number of combinations of 3 of the 10 digits is 720/6 = 120 combinations.

    • Its funny how every combination lock requires you to put the numbers into the lock in a particular order.  Perhaps they should have called it a permutation lock instead! lol

         You are right Thoth ! That's exactly correct.... it would be a permutation not combination. LOL 

          Hey look at this ..... I think they are saying you can get the first combination  permutation  number using our " MIRROR numbers" LOL  Check it out.... add 5 digits to the number. LOL

         HOW TO OPEN A MASTER COMBINATION LOCK

        How do you get those Master combination locks open when you've
        lost the combination? I found this file on a BBS and re-edited it to
        make sense
        . There was no reference to an author, so he will remain
        forever unknown.

        The Master Lock Company has made this kind of lock with a built
        in protection device
        . When you pull the shank of the lock (the part
        that springs open when you have given the lock the correct
        combination), the combination dial will not turn. That failure to
        rotate provides the key to being able to open a Master combination
        lock once you have forgotten the combination (something we are all
        prone to do!). There are three (3) numbers to a Master combination
        lock. You might want to get out a lock to understand easier.

        To determine the first number:

        Grasp the shank and gently pull on it. Do not pull it too hard
        or the dial will not turn at all! While pulling on the shank, rotate
        the dial to the LEFT until it will not rotate any further. Read the
        number under the index. Add 5 to this number and you have determined
        the first of the three numbers.

        To determine the second number:

        Relax the pressure on the shank and turn the dial completely
        around three to four times to the left. Rotate the dial to the right
        to the first number you determined. Then rotate the dial further to
        the right, bypassing the number once
        . When you have bypassed your
        first number, again gently begin pulling the shank and continue
        rotating the dial. It will eventually fall into a "groove" and the
        dial will cease to rotate
        . While in the groove, pull on shank and
        turn the dial. If the dial is lose and feels sloppy, go to the next
        groove
        . If the know will not rotate at all then you have determined
        the second number.

        To determine the third number:

        After getting the second number, relax the pressure on the shank
        and re-spin the dial. Then enter the first two numbers. After the
        second number, go to the right and at all the numbers give the handle
        a pull. The lock will eventually open if you did it right. If you
        can't do it the first time, be patient. Lock picking is not learned
        overnight and it takes time
        .

           Have a couple of locks around the house I don't know the combinations to, so...., easy getting the first number. Haven't got the second one yet 

          But this being lottery discussions, I was thinking....what if there were locks that only had 0-9 on the dial, not 0-30. Would be a heck of a basis to work a system out on, maybe that would be a good approach, to think of the pick 3 that way.

          Just a thought.
