On a lock of a safe deposit box a ten-digit code can be set. The code can consist only of four \( 1 \)s, three \( 2 \)s, two \( 3 \)s, and one \( 4 \). How many ways are there to set the code?
\( \frac{10!}{4!\cdot3!\cdot2!} = 12\:600 \)
\( \frac{10!}{4!+3!+2!}=113\:400 \)
\( 10!-4!\cdot3!\cdot5!=3\:628\:512 \)
\( 10! = 3\:628\:800 \)
