The number of 4-letter combinations depends on whether repetition of letters is allowed and whether the order matters. If repetition is allowed and the alphabet has 26 letters, there are (26^4 = 456,976) possible combinations. If repetition is not allowed, the number of combinations is calculated as (26 \times 25 \times 24 \times 23 = 358,800).

26 lower case letters + 26 uppercase letters + 10 numerals = 62 characters 624 = 14776336
From 4 letters, you can create three-letter combinations by selecting any 3 letters from the 4 and arranging them. The number of ways to choose 3 letters from 4 is given by the combination formula ( \binom{4}{3} = 4 ). Each of these combinations can be arranged in ( 3! = 6 ) ways. Therefore, the total number of three-letter combinations is ( 4 \times 6 = 24 ).
If order doesn't matter, 15 combinations and if order does matter, 360 combinations are possible.
256 iThink * * * * * It depends on combinations of how many. There is 1 combination of 4 letters out of 4, 4 combinations of 3 letters out of 4, 6 combinations of 2 letters out of 4, 4 combinations of 1 letter out of 4. Than makes 15 (= 24-1) in all. Well below the 256 suggested by the previous answer.
im assuming that any charcter can be a number or a letter: (24letters*10 possible numbers)^(4 digits)= 3317760000 possible combinations.

333 = 27 so it would be 27 possible combinations and for each added you would change it to 5 letters but 3 characters long then it would be 555 which = 126 and with the entire alphabet it would be 17576 (262626)

There are 210 4 digit combinations and 5040 different 4 digit codes.
2^n possible combinations
The letters M, A, T, and H can be arranged in different combinations by calculating the factorial of the number of letters. Since there are 4 unique letters, the total number of combinations is 4! (4 factorial), which equals 24. Therefore, 24 different combinations of the letters M, A, T, and H can be formed.
