About These Bases

Base 27

In base 27, each digit position represents a power of 27: the rightmost digit counts individual ones, the next counts groups of 27, the next counts groups of 27×27, and so on — the same place-value idea as base 10, just with 27 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.
