You can find this fun quotation puzzle, to combat early dementia and senility in us baby boomers, in several daily publications. I challenge us with the best ones out there.

The way it works is a letter stands for another letter. For example: AXYDLBAAXR is LONGFELLOW (does not apply to today's cryptogram).

Beware, the game is very addictive. If this is your first time, don't be intimidated, you’ll be solving them all within a few days. If you’re stumped, take a break and return to it.

PLEASE DO NOT post the answer in general comments, but DO post your time and how you made out.

You can certainly send your solution to my private reply, or if you need a hint for today’s Cryptogram ASK THE GROUP FOR HELP!

I suggest printing these out and work them on paper. If you need a little help you can copy and paste it to Hal’s Helper below.

You can then work on the puzzle without using pen and paper, but I recommend that you do NOT look at the letter counter.

HAL'S CRYPTOGRAM HELPER

One last request. Feel free to post a fun or clever clue, the more tangential to the quotation the better, but please don’t put the actual words of the quote in the clue.

Seems to be a problem...

Yes, I sent nikos a private post.

I used Hal — there is a misstep there. I did get it though.

C appears to be ‘misrepresented’

Only if you impose the constraint that the permutation matrix mapping plaintext to ciphertext has only zeros on the main diagonal. (Which is generally the case with good popular cryptograms.) Yes, element {3,3} is indeed 1. This constraint is actually a cryptological weakness, one that greatly aided breaking the German Enigma cipher.

And the ‘sudden’ downfall of Yamamoto

The Japanese did not use the enigma. The Japanese ciphers had worse flaws. For one thing vowels could only replace vowels. The reason was because Japanese telegraph companies charged more for consonants than vowels, and enciphered messages would have contained as many vowels as consonants, rather than a bias for vowels as in natural language. Diplomatic messages were transmitted via commercial cable companies, those in and out of the U.S. via Western Union.

I understand that...

I was merely pointing out that a sharp eye caught a flaw in the code and minds got together to ‘test the system’ and when they proved to be correct, Yamamoto paid for it.

Also had heard that one of the stories Tom Dewey sat on was that he was aware we had broken the Japanese Code and possibly knew about PH in advance - for the sake of National Security - he basically sat on the info rather than use it in the 1944 race.

Imagine today a pol sitting on something as important as that ..... HA...

Dewey is a distant cousin of mine. My sister’s middle name was Dewey. The Dewey story is complicated. Roosevelt did not have prior knowledge of the Pearl Harbor attack. The Navy intercepted and decoded the infamous 14 message. The last part instructed the Japanese ambassador to destroy code machines and secret documents. The Navy correctly interpreted this to mean that war was imminent. They wanted to send a warning to all stations in the Pacific. They had a one kilowatt transmitter, and there was an electrical storm effecting the ionosphere. The Army, down the hall, had a 10 kW transmitter that could punch through, but rather than depending on the Army, they sent the warning en claire via Western Union. Hence the sight of a Japanese-American WU messenger delivering a warning telegram to Admiral Kimmel against the backdrop of the burning wreckage of Battleship row.

JN25, the Japanese Naval code in use at the time of Pearl Harbor was only about 10% broken by December 1941.
