(In reply to the code I used by Charlie)

That's very similar to the code I used, but my method of keeping the digits unique was not as sophisticated, so I'll have to keep this in mind for future use.  And I only checked bases up to 15; I don't think my computer and/or algorithm is fast enough to get all the way up to 100!
