Hi Mr lowe,
this is a very interesting one!
Is it a shuffled or modified z340 with different symbols used? It has a lot in common with z340 (same raw ioc, same unigram frequencies). But different symbols and difference unigram row/column coverages. And it has more nGrams and no pivots.
yes it is a modified 340.. odds evens then each column raised 1 period.. no solve but high counts.
Thanks….thinking of hash marks as a way to count where 4 vertical lines (or 1’s) are made and the 5th by a line across the 4. And the impossibility of a solution may just be what he had in mind if as you say combining 3 codes would be possible.
Now I like the shuffling idea which reminds me of another conversation about shuffling cards and the way they are designed and how they can be read and the placement of the faces and numbers on them.
Forgive ignorant question but has anyone narrowed all this cipher work and the hours that must have been spent on it down or made a list of the most possible to the least? If not, maybe that would be a good idea. Start with the top and work way down.

I got a spike at period 1. Is this one to figure out if my spreadsheet is working correctly?
Hi smokie I hope you are well, no it was not to test. just an interesting easy (shuffle) that produced some high repeats it basically pulls a lot of period 19 into period 1… no solve of any merit..
I do have some checks to perform and some changes I can do. I was inspired to find an old code that had a bunch of + signs in a row because of this thread.. still looking for it.
cheers
A minor update:
I have written a small tool that creates word lists / dictionaries from text files (e. g. Project Gutenberg books). These serve as the basis for a dictionary attack. I also found a complete word list of about 479000 English words on the internet. My tool has used each of these words as a keyword for trapezoid encryption of start width 5. In the results I searched for long sequences of +-symbols. There were some hits with 6 consecutive + symbols. I also had word lists created from all Zodiac letters and used them as keywords. Unfortunately, the sledgehammer approach did not lead to a solution, and I would not have expected it.
Sorry if the is not the appropriate place to ask, but does anybody have a text from of the z340 that they can post here that I can "copy and paste" into my programs?
Every time I try to post code it cuts me off, I used some simple transposition ciphers for my responses, yet if I try to post them it will not work.

Go to http://zodiackillerciphers.com/cipher-explorer/
Pick the cipher you want from the Ciphers menu
Click "Edit" then "Copy cipher text". You now have the transcribed cipher text in the clipboard which you can paste wherever you wish.
If the forum garbles or cuts off the code, it is because it thinks some of the symbols are formatting codes. To get around this, use the "code" tag like this:

There is a button labelled "Code" in the toolbar of the edit box when making a post. It will insert the code tags for you; you just need to put the contents in between them.

I like this approach.
Hello,
today I have decided to stop working on z340. I had a great time here in the forum and would like to thank everyone. It is nice to exchange ideas and knowledge and work together on a solution. I was able to learn a lot and don’t see any minute spent with z340 as a waste of time. Anyone who starts such a hobby knows that it maybe will not bear fruit. Nevertheless, I was able to profit enormously from this time. I always enjoyed the atmosphere here in the forum, because there was always a respectful and friendly tone. Once again, thank you for that.
Of course I will continue to follow the threads, but I will no longer actively participate. If you have questions (e.g. about my tool "peek-a-boo") feel free to contact me.
While working on the trapezoid encryption, I looked at the pivots again. I would like to summarize and share my results and conclusions again. Sorry if it’s in a nutshell:
Pivots in plain text:
Pivots are quite common in plaintext (I posted some numbers above). If plaintexts of length 340 are shuffled randomly, the probability for pivots remains unchanged.
Pivots after homophonic substitution:
The more cyclically a homophonic substitution is applied to these plaintexts, the more often the pivots disappear.
I stick with the fact that the pivots were probably inserted intentionally, in order to lure by patterns on a wrong track. After the patterns were created, the remaining plaintext was substituted. For me this is a plausible explanation for the incomplete cycles in z340.
Especially around the pivots there are conspicuously many patterns. The trigrams IOF and FBC (inverted C) are also directly involved.
Let’s take Feynman 1 as an example. If you don’t know it: http://ciphermysteries.com/other-cipher … an-ciphers
Feynman 1 has three pivots if you write the text in a 19*20 grid. Here is a comparison between the transposed cipher and the plaintext:
Especially the "EEEO"-Pivot is immediately noticeable. An ideal start to set a wrong track in homophonic substitution. However, the pivots have absolutely nothing to do with the plaintext.
But before I start thinking again, I better stop. I wish good luck to all of you and that someone will find the solution soon. Don’t overdo it and take care of yourself!
Largo

You can try to create a paste here: https://pastebin.com/
Post the link to your paste on the forum. Then I can try to post the text directly here to see if I get the same problem.
Oh! I figured it out! In the "code box" it scrolls horizontally! Thats odd. But hey, as long as it’s there.

You can hit return/enter after each line of the cipher, to make it format better. Like this:
