As there are 4 numbers and they are all different, they can be arranged in:
4 choices for first number, leaving
3 choices for the second number for each choice of the first, leaving
2 choices for the third number for each of the choices of the first two, leaving
1 choice for the last number for each of the choices for the first three
giving:
number of choices = 4 x 3 x 2 x 1 = 24 possible orders in total.

Assuming leading zeros are not permitted, then: If repeats are not allowed there are 30 possible numbers. If repeats are allowed there are 60 possible numbers.
If the numbers can be repeated and the numbers are 0-9 then there are 1000 different combinations.

9!/6!, if the six different orders of any 3 digits are considered distinct combinations.
5 293 and 2 935 and 3 532 orders of numbers from least to greatest
4 of them. In a combination the order of the numbers does not matter.

The number of possible batting orders for a team with nine players can be calculated using the factorial of the number of players. This is represented as 9!, which equals 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1. The total number of possible batting orders is 362,880.
