Base 53 to Base 58

Base 53

In base 53, each digit position represents a power of 53: the rightmost digit counts individual ones, the next counts groups of 53, the next counts groups of 53×53, and so on — the same place-value idea as base 10, just with 53 distinct digits instead of ten.

Base 58

Base 58 works the same way: the rightmost digit counts ones, the next counts groups of 58, the next counts groups of 58×58, and so on, using 58 distinct digits.
