4!=4x3x2x1=24
4! = 4*3*2*1 = 24 of them.
If no digit can be repeated then there are 5 combinations, abcd, abce, abde, acde and bcde. If you regard abdc as different from abcd then each of the 5 basic sets could be arranged 24 ways and the total would be 120 combinations.
There are 24C12 = 24!/[12!*12!] = 2,704,156 combinations.
There are 24C12 = 24*23*...*13/(12*11*...*1) = 2,704,156 combinations.

Three combinations: 23, 24 and 34
24C7 = 24!/((24-7)!7!) = 346,104.
