Observations

Yeah it’s long, real long but… We know that 3 codes are usually released so we have to assume that there are 3 codes is there. Notice some numbers are always repeating. Notice the hint also.

[hint]One code uses the 7s & 8s, the 2 others use the rest of the string and use a ciphers that only need 2 bits.[/hint]
