Okay, i really suck at math and i really need to solve this.

I have all these characters and i want to know how many up to 3,4,5,6 combinations can i have for the following 62 characters (Repetition is allowed).

0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMN OPQRSTUVWXYZ

4 characters eg :
could be the following:

what he said, here why:

entry: _ _ _ _
1st digit can be any of the 62 characters
2nd digit the same, same for the 3rd and the 4th
so its 62x62x62x62

no repetition it would be:
62 choices for the 1st digit x 61 choices for the 2nd digit x 60 choices for the 3rd digit x 59 choices for the 4th digit.
each time the choices has been decreased by 1 because it's taken by the preceding digit.

he is saying that for for n permutations it is actually:
for n permutations (here 4) what he wants is perm(4) + perm (3) + perm(2) not only perm(4)

the answer is
62^1+62^2+...+62^N where N=3,4,5,6 (or whatever you choose it)
