That gives me an idea. Test the message by designated areas for cycle scores. Designate an area, and calculate the cycle score with all of the symbols in the message where only those symbols are in the area. For example, designate all of the cells in a diagonal row. Then calculate the cycle scores for the message after deleting all of the symbols in the message that do not appear in that diagonal row. Do that with a lot of areas of the same size and shape to see if there is one area or shape that has a really high cycle score. See if that can be used to identify repetitive patterns in the plaintext.
For the idea two posts above, cast the message into 19 x 18, then slide three columns down one position. Then slide the next three columns down two positions. Do that with different combinations of three columns. Test horizontal rows to see if you get higher cycle scores.
