%e The code is decrypted by looking at the first letter of the chapter for each number, resulting in ERPERDJLWTEEOOGT. Decryption is performed using a columnar transposition cipher, termed a "Caesar Square" cipher in the book (this is unrelated to the Caesar cipher). The letters are arranged into a square:
%e ERPE
%e RDJL
%e WTEE
%e OOGT
%e and read from the top down.
%e ERWORDTOPJEGELET.
%e Add spaces and you get the plaintext, "Er wordt op je gelet" a reference to the NSA's monitoring systems.
%Y Cf. A121374.
