wow,, what a disappointment.

1. Several cipher symbols deciphered to 2 letters of the alphabet, one even a question mark as the second. ( I was under the impression this characteristic was the biggest flag of them all when it comes to a forced solution).

It’s normal for several cipher symbols to decode to the same letter.

Zresearch-

In a homophonic substitution cipher:

1) A single letter may have multiple substitute symbols.
2) A single symbol may only substitute for a single letter.

Do you see the difference there?

Sorry if I wasn’t clear. What I meant is what Glurk is referring to that I have a problem with. Several symbols have been deciphered into 2 different letters of the alphabet rather than just one.

If that road is to be gone down then past solutions might as well be accepted like Starliper or Cecil.

Here it is…

Zodiac turns in his grave.

As I’ve posted before, I believe the Z340 is gibberish. But, I don’t waste my time trying to solve it, so who am I to say?

Sorry if I wasn’t clear. What I meant is what Glurk is referring to that I have a problem with. Several symbols have been deciphered into 2 different letters of the alphabet rather than just one.

"Several symbols been deciphered into 2 different letters", is an understatement, there are 10 symbols that represent 3 unique letters each, and about 20 symbols that represent 2 unique letters each.

The first part of the 340 you can nearly type in anything ..this was a partial "solve" by doranchacs? solver. I know its not a solve but its better than History Channels. you can even get a bottom line that fits as well because of the structure.

My girlfriend has been watching me work on the 340 for four years now…

Girlfriend: "If it was so easy to solve, then why didn’t you solve it a long time ago?"

Then I tried to explain it to her, about the count of ciphertext, count of symbols, multiplicity, polyphones, etc. She wants to believe me that the History Channel has a bogus solution, but I have to prove it to her. So we have a date soon where I am going to try to do that, and I have to be prepared.

I count 19-20 polyphones, symbols that represent different letters color coded. If we made up some rules like the people on t.v., such as "the symbols that look like letters really are just those letters, hiding in plain sight", and allow for up to 20 polyphones, I wonder what other creative solutions we could come up with. Even though the people on t.v. didn’t even stay with their own rule.

EDIT: Hint, that is a challenge to the rest of you.

The History Channel has some "good" ( an adjective taught in law school ) lawyers who drafted a contract giving the t.v. producers a great deal of control over the content of the show, and probably most of the dialogue. The show had to come up with a solution because that is how people are going to watch it. Most people aren’t going to want to see cryptanalysts work really hard and come up with nothing. So it is somewhat unfortunate because now a lot of people are going to think that the 340 is really solved when it really is not, but the "solution" can be discredited and we can still work on it.

Oh, I forgot to put the Richard Nixon part in there. I may do that later. Right now taking a big rest.

She wants to believe me that the History Channel has a bogus solution, but I have to prove it to her.

My wife just lolled when I told about the show’s conclusions. She has seen other programming from them and was not surprised

I think what confuses many is the name of that channel. It hints about them being historically accurate or something, which they really are not. I don’t think any of their programming would be regarded as "documentaries" in Europe. It’s just entertainment.

I am sorry but I must reiterate. How do Knight and Bauer try to run with this completely BS proposed solution? After even supposedly running it by the code team before taking this run of the mill BS outside the team?

I do not not believe for a minute Dave, Ryan or the Google guy are on board. How could they be when this hunk of poo is worse than Starliper and cecil when it follows the same loose parameters. At least they had a full decipherment.

I can not stress the bafflement stemming from this. Knight and Bauer should not only be ashamed but embarrassed as well. This is down right wrong on so many levels and I am seriously pissed. I am on the brink of losing respect for Knight and Bauer over this.

You (and everyone) should look at Oranchak’s article from a few years back here:

The HC solution manages to do almost ALL of the wrong things, LOL.

Exactly! That is why I do not believe Oranchak and Garlick are on-board with Knight and Bauer presenting the BS they took outside the team.

Sorry to beat a dead horse but I simply cannot believe Knight and Bauer put that out there actually calling it a possible solution.

They honestly look foolish and I hate saying that because I respect them a great deal. I just do not get it.

Knight didn’t seem all that excited either, imo. I mean, this would be HUGE and I didn’t feel the energy. Interesting too, two big wigs outside of the team seemed to think there was something to it, but no comment from the FBI is quite telling. At least I think so. Although, maybe they don’t necessarily speak "publicly" in that sense.

There’s no logic to their solution whatsoever. It’s stupid and all those code guys should be embarrassed in putting their name to that.

I could understand if some of the letters deciphered to themselves and the rest fit a proper pattern. That would be believable. But the thing jumps all over the place which is the first obvious sign that it’s wrong.

Also Z just happens to start the message the same as the Dahlia letter. Puhlease, that doesn’t sound like him at all. Never once did Zodiac mention other well known killers. He was all about himself.
