Making Light:  Bub, bar cher flap! ::: March 22, 2007, 08:14 AM

A guy writing a screenplay once asked me if I could find a
palidromic word square in English.  The only 5x5 in an online
version of the OSPD was

SEMES
EDILE
MINIM
ELIDE
SEMES

I hadn't thought of a "four-way" word square, in which we don't
require a palindrome, only that the square be made up of words in
all four rotations.  There should more of them.
