Cracking Master Combination Locks



I've come across the following information:

The three numbers in the combination to a Master Combination Lock have the following relationships:

The first number modulus 4 = the third number modulus 4;

and

The second number modulus 4 = (the third number modulus 4) +/- 2.

If this information is correct, the following tables showing possible numbers in a combination should be valid:

Table 1

1st Number Possibilities  1  5  9 13 17 21 25 29 33 37
2nd Number Possibilities  3  7 11 15 19 23 27 31 35 39
3rd Number Possibilities  1  5  9 13 17 21 25 29 33 37


Table 2

1st Number Possibilities  3  7 11 15 19 23 27 31 35 39
2nd Number Possibilities  1  5  9 13 17 21 25 29 33 37
3rd Number Possibilities  3  7 11 15 19 23 27 31 35 39


Table 3

1st Number Possibilities  2  6 10 14 18 22 26 30 34 38
2nd Number Possibilities  0  4  8 12 16 20 24 28 32 36
3rd Number Possibilities  2  6 10 14 18 22 26 30 34 38


Table 4

1st Number Possibilities  0  4  8 12 16 20 24 28 32 36
2nd Number Possibilities  2  6 10 14 18 22 26 30 34 38
3rd Number Possibilities  0  4  8 12 16 20 24 28 32 36

The number of possible combinations to a Master Combination Lock is 64,000 ( = 40 x 40 x 40).


If the above four tables are valid, the number of possible, valid combinations is only 4,000 ( = 4 x (10 x 10 x 10)).


Still a considerable number; however, it's reduced by a factor of 16.


Before going further, I would like to confirm the above four tables show all valid, possible combinations to Master Combination Locks.

If you have a Master Combination Lock, would you compare the combination to the lock against possibilities in the tables?

Does the combination to your lock appear as a possibility in the tables?

Mine appears as a possibility.

ye i found mine...i had fprgotten my combo but i new that my second number was 30 so i looked for the table with 30 in #2 and then i just went with the low numbers for the first and third combos and it opened thanx

 

[meee]

yeah it works man.
there are several website about this.
once u have used the sticky points method to find the last number, there is only like something like 64 combinations and u can easily go through these combinations to find it out.
