    Default Exponential Growth

    I'm heading forward with my ADFGVX decrypter.

    Just a short question, since I'm not the greatest math genius.

    I just need a formula that can calculate the amount of possible combinations of chars where no char appears twice:

    For Example:

    ab = 2
    (ab,ba)
    abc = 6
    (abc,acb,cab,cba,bca,bac)

    Anyone ? : D

    Yup. That's the formula he's looking for.
