Base 42 to Base 48

Base 42

In base 42, each digit position represents a power of 42: the rightmost digit counts individual ones, the next counts groups of 42, the next counts groups of 42×42, and so on — the same place-value idea as base 10, just with 42 distinct digits instead of ten.

Base 48

Base 48 works the same way: the rightmost digit counts ones, the next counts groups of 48, the next counts groups of 48×48, and so on, using 48 distinct digits.
