I had to use my knowledge of Math to figure out the combination of my bike lock that had been accidentally lost.
There was no way I could recover the combination, because it was not written anywhere. I had to try one by one.
The lock was cylindrical, with a 6-6-6-6 style. There are 6 options for each of the 4 positions. 6 to the 4th power, that is 6x6x6x6 = 1,296 possibilities.
I tried 1,186 of the possible combinations.
(6x6x6) x5 = 1080
(6x6) x2 = 72
(6) x5 = 30
