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.

How could you find the number of different combinations of 6 letters in a computerpassword?
This depends what you define as a "Letter". Are you stricly talking about the 26 characters in the alphabet [a-z], or do you consider "A" not the same as "a"? If capitalization matters, we now have 52 possible values for the first character. What about numeric digits [0-9]? If they count, there are 62 possible values for each character. Maybe some special characters can be used, but we won't delve into those. Therefore, if the length of your string is 6 "Letters" and each letter may be any one of 62 values... use the following calculation: (62) x (62) x (62) x (62) x (62) x (62) = 56,800,235,584 total combinations Hypothetically if you could not use the same character twice, you would have less possible combinations: 62! - 56! is the same as: (62) x (61) x (60) x (59) x (58) x (57) = 44,261,653,680 total combinations

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.
