In VIM at 3am, because my headache won't let me sleep and my latest round of performance tests won't finish for another 90 minutes or so.

1. Ctrl-V
2. :%s/\s\+\*//
3. :%s/.*\s.*\n//
4. :%s/.*/\U&/
5. :%s/S$//
6. /^.[AHIMOTUVWXYZ]\+.$

Yields (unless you also chose ethnicity lists) the six answers referred to. Only one is a palindrome if you remove the first and last letters.

Oh, and "Z" doesn't give you errors, but it's also not symmetric, so it would only be allowable as the first or last letter, not as the reflected palindromic center of the word.

Fun stuff, even if you did the heavy lifting. But then again, my brain isn't used to functioning at this time of night anymore, so I'm content just to implement the pseudo-code and try (again) to go to sleep. And I don't have to be curious, because I know the answer.
