How many different 3 letter combinations are there... for example airports are typically LHR LGW LAX etc how many different possible combinations are there?
There are 26 letters in the alphabet.
If letters may be repeated in the airport code, then there are (26 x 26 x 26) = 17,576 possibilities.
If adjacent letters can't be duplicates, then there are (26 x 25 x 25) = 16,250 possibilities.
If all three letters must be different, then there are (26 x 25 x 24) = 15,600 possibilities.
