A word square (n-square) consists of a n rows, each containing a different n-letter word, so that the first column has the same word as the first raw, and so on. A palindromic square is a word square in which the words are palindromes, with as many as possible being different. The investigation reported below was inspired by Zoran Radisavlijevic's article (W05-178).
