A four-lettered palindrome has the pattern ABBA, where the first and last letters are identical and the second and third letters are identical. The first position A can be filled by any of the 26 English letters. The second position B can also be filled by any of the 26 letters. By the multiplication principle, the total number of such palindromes is 26 multiplied by 26, which equals 262.
