About These Bases

Base 51

In base 51, each digit position represents a power of 51: the rightmost digit counts individual ones, the next counts groups of 51, the next counts groups of 51×51, and so on — the same place-value idea as base 10, just with 51 distinct digits instead of ten.

Base 20

Base 20 works the same way: the rightmost digit counts ones, the next counts groups of 20, the next counts groups of 20×20, and so on, using 20 distinct digits.
