36*36*36*36*36*36
im assuming that any charcter can be a number or a letter: (24letters*10 possible numbers)^(4 digits)= 3317760000 possible combinations.
With a Latin alphabet of 26 letters and the 10 digits 0...9, and allowing for repeats, you get: 36^4 = 36 × 36 × 36 × 36 = 1,679,616 combinations. If you were to include both lower and upper case characters, the number of possible combinations goes up (due to 26 lower case letters + 26 upper case letters + 10 digits = 62 characters to choose from): 62^4 = 14,776,336.
Total of 720 combinations:1 --- 12 --- 23 --- 64 --- 245 --- 1206 --- 7207 --- 5040.......Notice that:A --- BC --- DE --- FG --- XIn this sequence, if you wanted to know "X", it would be equal to FxG, and that is the key to this sequence. Why does it happen?Well, if, lets see, for instance, if 2 digits (0 and 1) have a possible of two combinations (10 and 01), then 3 digits (0, 1 and 2) will have a possible of six combinations: 012021And equivelent, but switching 0 with either 1 or 2, making it repeat itself 3 times.Eventually, we will end up doing 2 (number of combinations with 2 digits) times 3 (number of digits of which we want to know the number of unique combinations possible), totallizing 6 (our wanted-to-know number)
There are 45 combinations.
The short answer is 1000. This is very easy to visualise: Simply consider each number in the combination to be a digit in a decimal number. We then end up with a three-digit number. Such a three-digit number ranges in value from 000 to 999, or 1000 unique combinations.

The letter after the serial number is called the "suffix letter" and is simply used to provide more unique combinations of characters. Numbering normally starts with 00000001A. The numeric part is incremented until it reaches 999999999A, then it's reset to 00000001 and the suffix is increased to "B". Because there are 99,999,999 possible unique numbers and 26 unique letters, it's possible to have nearly 2.6 billion unique numbers for each Federal Reserve District's bills! Note: 00000000 is reserved for "specimen" or test notes, so it never appears on circulating bills.

ASCII (American Standard Code for Information Interchange) is the most common format for text files in computers and on the Internet. In an ASCII file, each alphabetic, numeric, or special character is represented with a 7-bit binary number (a string of seven 0s or 1s). 128 possible characters are defined.

There are 26 alphabetic characters (a-z) and 10 numeric (0-9) which together form 36 alphanumeric characters. If you include capital letters, then you have 62 (36 + 26) alphanumeric characters. 62 * 62 * 62 = 238,328

When rolling 6 dice, each die has 6 faces, resulting in (6^6) combinations. This calculation yields a total of 46,656 possible combinations. Each combination represents a unique arrangement of numbers from the six dice.
The production of unique genetic combinations may help an organism better adapt to its environment.
The IFSC Code is 11 digit alpha numeric number and the first four characters uniquely identify the bank and the next four characters are control characters and the last three digit number uniquely identify the bank branch. IFSC Code for every Branch of the banks is unique.
There are 45 combinations.
The number of possible combinations that can be formed from a protein's monomers depends on the number of unique monomers present in the sequence and the length of the protein. The total number of combinations can be calculated using the formula 20^n, where n is the length of the protein in terms of monomers, assuming there are 20 different amino acids commonly found in proteins.
