There are 26 characters in the English alphabet, plus 10 numerals.
The total amount of combinations for 2 alphanumeric chars is given by
(26+10)²=1296
If you also include capital letters then the result is
(26+26+10)²=3844
Only letters gives
26²=676
it is 26
26 lower case letters + 26 uppercase letters + 10 numerals = 62 characters 624 = 14776336
Decide what symbols you want to allow. For example: 26 uppercase letters + 26 lowercase letters + 10 digits = 62. Or less, if you don't want to distinguish uppercase and lowercase; or more, if you want to allow certain special symbols such as spaces, hyphens, etc. Raise this number to the sixth power, if you use 6 characters.

Letters - 26Numbers - 10Total chacters - 36If characters can be repeated (QQ and 44 are acceptable): 36 x 36 = 1,296If characters can't be repeated (GG and 99 not acceptable): 36 x 35 = 1,260If characters can't be repeated and the sequencedoesn't matter (X7 and 7X are considered to be the same): 630
it is 26
26 lower case letters + 26 uppercase letters + 10 numerals = 62 characters 624 = 14776336
im assuming that any charcter can be a number or a letter: (24letters*10 possible numbers)^(4 digits)= 3317760000 possible combinations.
There are only alphabetic combinations since there are no numeric characters in letters.The answer assumes thatyou mean the modern Roman alphabet,letters may not be repeatedupper case and lower case letters are considered to be the same,you did mean combinations and not permutations.Then the answer is 26C5 = 26*25*24*23*22/(5*4*3*2*1) = 65,780

Letters and numbers only. No symbols, punctuation, or special characters. IE abcdefghijklmnopqrtsuvwxyz1234567890
The term alpha characters refers to those characters that are letters. This is in contrast with numeric characters, which are numbers.
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.
