You can put this solution on YOUR website!
Since order matters, you can either compute 45 P 4 or you can realize that there are 45 choices for the first slot, 44 for the second, and so on and then multiply those choices to get:

45*44*43*42 = 3575880


So there are 3575880 different selections possible.
