There are a lot of them, so I'm sure you don't want us to list them all.
If you want 0-9, and are happy with repeat digits, then it's 10*10*10*10 = 10000 combinations.
If it's 1-9 and are happy with repeat digits, then it's 9*9*9*9 = 6561 combinations.
0-9 without repeat digits is 10*9*8*7 = 5040 combinations
1-9 without repeat digits is 9*8*7*6= 3024 combinations
A 4-digit number can range from 0000 to 9999, which includes all combinations of four digits. Since each digit can be any number from 0 to 9 (10 options), the total number of combinations is calculated as (10^4). Therefore, there are 10,000 different combinations for a 4-digit number.
There are actually 8,998 of them . . . all of the counting numbers from 1,000 to 9,999 . The list is too large to present here, but if you can count, then you'll have no trouble generating it on your own.
You have 9 options for the first digit; whichever digit you choose you have 8 options for the second digit, 7 for the third digit, 6 for the fourth digit - so you have a total of 9 x 8 x 7 x 6 different combinations. Sure I could make a list, but that would be rather boring - and utterly useless as well.

To find the number of combinations of the digits 1, 2, 3, 4, 5, and 6 that form numbers less than 500, we can consider the constraints based on the first digit. If the first digit is 1, 2, or 3, all combinations of the remaining digits can be used. If the first digit is 4, only combinations that result in a two-digit number can be formed. The total combinations can be calculated based on these conditions, but generally, you can form various 1-digit, 2-digit, and 3-digit numbers, totaling around 120 distinct combinations.
This question needs clarificatioh. There are 4 one digit number combinations, 16 two digit combinations, ... 4 raised to the n power for n digit combinations.
There are more than 4.

I can't
There are 840 4-digit combinations without repeating any digit in the combinations.

There are 210 4 digit combinations and 5040 different 4 digit codes.
i would like a list all possible 4 digit combination using 0-9

7043.......there are 4 digits. In 'normal' numbers that are greater than zero then zero is superfluous as the first digit, for example we write 437 NOT 0437. Then, there are 3 possible numbers for the 1st digit (3, 4, 7) and 4 numbers for the 2nd, 3rd and 4th digits.(0,3,4,7). The number of valid number combinations is, 3 x 4 x 4 x 4 = 192.
