Again, thanks to everyone who has been giving me lot of helpful info.  :D

If I want to also look for palindromes that are anywhere between 1 and
4 characters in length, what would I do?  I am looking at this : (^|\
)([A-Za-z])([A-Za-z])\3\2($|\.|\ )  and I am not seeing how to break
it down so I can find palindromes bigger or smaller than 4 character's
in length. Could someone explain it to me?  I am very curious.  :)

Thanks!
