About These Bases

Base 17

In base 17, each digit position represents a power of 17: the rightmost digit counts individual ones, the next counts groups of 17, the next counts groups of 17×17, and so on — the same place-value idea as base 10, just with 17 distinct digits instead of ten.

Base 18

Base 18 works the same way: the rightmost digit counts ones, the next counts groups of 18, the next counts groups of 18×18, and so on, using 18 distinct digits.
