Some years ago, I pointed out some ciphers from Louis XIV's time can be arranged in a table to reveal alphabetical arrangement of elements. (This characteristic was known to John Wallis, contemporary Engklish codebreaker.) I have now added images to specifically show such regularity for two ciphers from 1689 (in addition to similar images for 1693 and 1702 ciphers) in
"French Ciphers during the Reign of Louis XIV" and
"Specimens of French Cipher (1689) Printed in John Wallis' Opera Mathematica".
