Hey JeanLuc, Maybe you can add base 28 too... I added few factorization to the DB for 28^n.
I saw you added higher bases, like 439 (?) and I don't know what reason you had, but my opinion is that 28 makes more sense than 439 or 10^x (6^n, 28^n or even 496^n can be seen as powers of perfect numbers, or "powers of drivers", in fact that was what "tickled" my interest for base 6 in the past).
