I want to know what is the longest palindrome word.
The number I am thinking of is 80808. This is a palindrome. However, it is more than a palindrome, because it can be flipped or mirrored and will still read the same way. Is there a word for this?
Somewhat related to this question, but I'm interested in a phrase, not just a single word. The longest I am aware of is A man, a plan, a canal: Panama Are there longer palindromic phrases?
