About These Bases

Base 61

In base 61, each digit position represents a power of 61: the rightmost digit counts individual ones, the next counts groups of 61, the next counts groups of 61×61, and so on — the same place-value idea as base 10, just with 61 distinct digits instead of ten.

Base 28

Base 28 works the same way: the rightmost digit counts ones, the next counts groups of 28, the next counts groups of 28×28, and so on, using 28 distinct digits.
