Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%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.
