If three numbers are entered in different combinations, the output is the same. For example, if the setting of an encode is 1 2 3 and it is entered to encode ABC, the output is '456'. If 'ABC' is encoded with the setting, 2 3 1, it outputs '456' as well. This reduces our combinations greatly; we need each combination to do a different change.
