26 letters in the alphabet.
10 numbers (0 through 9)
you have 3 letters followed by 2 digits.
that would be:
26*26*26*10*10 = 1757600 possible combinations
here's how it works.
assume only 3 letters (abc) and only 2 number (01) are possible in each position.
assume only 3 positions (2 letters and 1 number)
that would be 3 * 3 * 2 = 18 possible combinations
they would be:
aa1
aa2
ab1
ab2
ac1
ac2
ba1
ba2
bb1
bb2
bc1
bc2
ca1
