There are 210 of them, and I regret that I do not have the time to list them all.
The answer is 31C5 = 31!/[26!5!] = 169,911

The question, as stated, cannot be answered because there are only 26 = 64 combinations. The order of the numbers in a combination does make a difference so 134 is the same as 143 or 413 etc. There are 1 combinations each of 0 and 6 of the numbers, 6 combinations of 1 or 5 numbers, 15 combinations of 2 or 4 numbers, and 20 combinations of 3 numbers. The list includes the null combination - that is the combination consisting of none of the numbers.
There are only 5 distinct combinations of 4 numbers.(1234, 1235, 1245, 1345, 2345) C = 5! / 4!But there are 120 distinct combinations in distinct order (i.e. 24 ways to order each abcd).abcdabdcacbdacdbadbcadcb

It depends. If you can only use each number once, there are 720 combinations. If you can use numbers multiple times, then there are 1000 combinations, by using all numbers from 000 to 999.
The four numbers that can be used in combinations or differences to make all numbers from 1 to 30 are 1, 2, 4, and 8. These numbers are powers of 2, which allows for the creation of all numbers from 1 to 30 through various combinations and differences. By using these four numbers strategically, one can generate any integer between 1 and 30.
Only one.
The answer is 31C5 = 31!/[26!5!] = 169,911
There is only one combination. In a combination the order of the numbers does not matter so the only combination is 0123456789. This is the same as 1326458097

To find the number of combinations to make 40 using the numbers 12 and 4, we can use a mathematical approach. Since we are looking for combinations, not permutations, we need to consider both the order and repetition of the numbers. One way to approach this is by using a recursive formula or dynamic programming to systematically calculate the combinations. Another approach is to use generating functions to represent the problem and then find the coefficient of the term corresponding to 40 in the expansion of the generating function. Both methods require a deep understanding of combinatorics and mathematical algorithms to accurately determine the number of combinations.

Yuo can make only one combination of 30 digits using 30 digits.
If the numbers are allowed to repeat, then there are six to the fourth power possible combinations, or 1296. If they are not allowed to repeat then there are only 360 combinations.
