Base 39 to Base 59

Base 39

In base 39, each digit position represents a power of 39: the rightmost digit counts individual ones, the next counts groups of 39, the next counts groups of 39×39, and so on — the same place-value idea as base 10, just with 39 distinct digits instead of ten.

Base 59

Base 59 works the same way: the rightmost digit counts ones, the next counts groups of 59, the next counts groups of 59×59, and so on, using 59 distinct digits.
