Let me know all your thoughts about it.

I applaud your efforts, Eduard. I think looking for certain Z-ish words in the code, like AFTERLIFE, is a good idea. PARADICE would be another. Of course he may have left them out, Because they are present in the 3-part cipher, but its still worth a try.

I wonder if you could post an ASCII version of your solution, in 17 x 20 format. Ie starting with "OINEED" ... This would help with subsequent computerized analysis.

Since you see the 340 cipher as being a MAP, and since you find a "giant Z" through the cipher, I'm surprised you do not mention the "giant Z" theory, which apperently is discussed in "Times 17" by Penn. Even though Jake called this theory into question:

http://www.zodiackiller.com/messageboard/messages/15/115.html?970025784

The similarity between it and what you find is unmistakeable.

One thing I'm not clear on: The characters you marked with Blue Asterisks as not meaning anything, how do you distinguish these from the other characters which do not represent letters, but instead represent blocks in your bay-area map?

Lastly: You ask the question on your website:
" What is the change (sic) you can find ...hidden "digital" map of the area that
Zodiac kept in fear."


You could answer this question by generating RANDOM arrays of around 100 black dots within a 17x20 grid, then checking if you can use 1/3 of the points (and ignore 2/3 of them) to form patterns similar to those on the map. My guess is that it will not be hard to correlate such digital map, with the SF Bay area, or for that matter with a map of say, Die Netherlands.

Keep up the good work, Obiwan

Hi Obiwan,

I will post a ASCII version of my solution for you next week ( I have not much time at this moment). Thank you for wanting to investigate my solution in ASCII. I am interested what you could find in it.

I put the "Big Z" characters also in block but coloured them blue (and not black as the others).
Maybe on the map, they can form a big cross to show a certain location?

I must agree with you, anything can be seen in the blocked version of my code but....
Look how centered the SF Bay area is in the code just like on a map.
I could have found something like Mickey Mouse, The Netherlands, A clown etc. But still I find it very significant to find the Bay area map in it, the Bay featured in the middle, and the other dots on places of crossroads.
I found it interesting enough to put online.
Even without the 2nd and 3rd layer I think my solution is interesting.

Eduard

P.S. to all you ALA fans out there...Look at the first 3 characters in the 2nd row of my solution.
They are "L","E" and "E". Could this be "LEE" ?

Thanks Eduard. While I don't plan any deep analysis, I have so far noticed the following things about your solution:

Ciphertext "G" represents "G" on line 1 but
Ciphertext "G" represents "S" on line 3

Ciphertext ")" (Circle with horizontal line-like greek THETA) represents "C" on line 2 but
Ciphertext ")" represents "I" on line 3

I might add here that this THETA symbol, which I designate ")", appears as the 2nd to last character in lines 17 and 18, though the line 17 char. is a bit filled in. In lines 17 & 18 you have this character representing "L" and "I" respectively.

Square-Lower Left Filled (my "\") represents "F" in line 2 and "A" in line 4.

Backward-Y ("y") represents "I" on line 3 but represents "O" on line 10.

I have not had time to find all the multiple representations, like those above. Eduard, my understanding was that your solution, as opposed to Zanders, intended to represent each ciphertext character as only one plaintext character...am I wrong about this? (in fact I believe Zander's "final" version only has two or so of these multiple characters). Perhaps the multiple characters crept in when you merged your two best solutions.

The advantage of using a computer to do the character replacement is that if you do assume each character = 1 letter then when you change your mind while decoding, all of those changes are reflected automatically throughout the code.

ps.

Obiwan,

Sometimes Z used a B for more than one character.
He then filled in the top or bottom of the B.
You are right I intended to represent each ciphercharacter as a plain text character.
I believe this cipher can be solved without a computer. It was made without a computer and it was intented to be solved (in a time when there were not so much computers as today).
Thanks for spending time on it.

Eduard

P.S. I will be offline for 2 weeks.

Eduard, I take it you mean: as a SINGLE plain text character

If so then when you get back perhaps you will want to look over your solution and resolve the multiple meanings I mention above plus any others. The problem with multiple meanings for a given letter is that if this is allowed, (without specified rules for encoding) then practically any string of text can be considered a solution.

Having said that, I must admit that the 3part cipher uses Triangle-Solid and Triangle-Dot (which may have been one symbol orignally) to represent both A and S. But other than that, each symbol represents a unique letter.

Edwuard,
Your "wait and see" at the end of the 340 is like Z's desk bottom poems' "Just wait till next time."It has the same ring to it.

Dave Peterson and a code expert took the 340 and did some anagramming for fun.They found starting from the third character, in from bottom right ZODIAK and the cross/circle("part of fortune" in astrology)that precedes it as a symbol of his name also.FBI at line ten on right characters two -four.TOM(Tom Johnson Napa Under Sheriff?)from right line 12 6-8 chracters.Line one on rt.five symbols as LT TO GOD(recall In the Beginning...Z stamp).Of course,I would see something there!This is all in fun.Line nine on left 7-9 as ZERO a Davis victim and/or as the SPD 'score.'More later.Thought I'd break up the hard core stuff with a little pastime musing.More later-maybe!

By obiwan (Obiwan) (ciw2.ciw.edu - 192.70.249.40) on Friday, March 01, 2002 - 06:24 pm:

Howard, the odds that random characters from the 340 ciphertext or any other ciphertext can be anagrammed to spell 3 and 4 letter words are VERY GOOD. If you were UNABLE to find any such words as the ones you mentioned I would be stunned.

Obiwan,
If you want a copy of the 340 both men worked on I would be happy to send you a copy.E me.
