383,203 row and column palindromic order 5 Word squares can be built from the titles of the articles in the English Wikipedia but only 66 of those also contain palindromic words on both diagonals. Some of these squares with words on all 24 projections contain as many as 10 distinct words leading to a number of interesting selections, while squares with fewer have a high degree of symmetry which brings its own beauty.

There are a great many more order 4, but the count is reduced to a reasonable number when the all uppercase titles are removed.
