Question: In Mark Salas, the 1991 Detroit Tigers had probably the only palindromic player in major league baseball (certainly, the only palindromic catcher). A palindrome is a word that reads the same forward and backward, like SALAS.
(a) How many five-letter palindromes (not necessarily real words) can be made from the letters of the English alphabet?
(b) How many eight-letter palindromes are possible?
(c) How many "words" not exceeding eight letters in length are palindromes?
(d) One of the most famous palindromes of all time is one which might have been uttered by Napoleon (had his native tongue been English): ABLE WAS I ERE I SAW ELBA. How many palindromes (not necessarily of real words) are this of this length?
