While thinking about letters, numbers and palindromes, I realized (am sure many of you also would have) that there are 7 English letters, namely, H, I, N, O, S, X and Z that read the same upside down. It is not difficult to further realize that there are 2 numerals, namely, 0 and 8 that read the same upside down.
I was stressing my brain to find out palindromes made of these letters so that they read the same even upside down and not just left to right or right to left. I could find two words - NOON and SEXES. If you find more, please do post them as comment.
