@Holmes201,

I don’t have a codebreaking background and rolled into it around the summer of 2014. What exactly is your idea?

@Holmes201,

I don’t have a codebreaking background and rolled into it around the summer of 2014. What exactly is your idea?

I held the 340 up to a mirror. The symbols look different in a mirror image. It changes the whole coding. Perhaps putting the symbols in the mirror image into a code breaking program could find some solution.

There are two "factoids" in support of the message being encoded from right to left (a mirror image, as you say):

1) Bigram repeats are higher in the right-to-left, top-to-bottom direction: 29 repeats (in that direction) vs 25 (in normal direction)
2) As has been mentioned by others, "distance 14" bigram repeats peak in the right-to-left direction (at 40 repeats).

But the folks here have already run the right-to-left direction through the solver programs with no luck, so there must be something else going on. Hard to say if it involves reading from right to left.

Yes I understand what you’re saying. What I’m trying to explain is to hold the 340 page up to the mirror. Forget about left to right, right to left. Transcribe what appears in the mirror, the symbols are different. It’s not going to be anything to do with the letter order, it’s what the original letters become in the mirror. There are changes to the lettering.

What the "letters" in the cipher look like have absolutely no difference to solving it. All we need to know is which symbols in the cipher are the same, and which are different from one another. Internally, in the computer, they are all represented by numbers anyway. Yes, there are simple encryption methods (or, rather, obfuscation methods) that either mirror the letters, or half of each letter (top/bottom or left/right), but they can still be cracked without knowing how each letter was transformed. I can also think of steganography that could’ve been used in Z340, for which it would’ve been super important what each symbol look like, but there are no signs that steganography was used as the symbols are not sufficiently different from one another to carry enough hidden information among them. I think someone even analyzed the placement of each symbol on each line and found no traces of anything unusual. I think some of the lines/rows where spaced further apart, but individual symbols were pretty well lined up and evenly spaced in each line.

So 14 symbols or characters for a few of the most commonly used letters would be insane huh?

So, you want a challenge, eh? Alright. Here, I present to you daikon6:

It’s longer, 440 symbols, so it should be easier to solve. 15 bigrams encoded as one symbol each (1-to-1 substitutions). The rest are normal homophones (52), no typos, no polyalphabetic symbols, no transcription errors, no super-rare words, no poetry, no number sequences, no tricks. I did use a more obscure text that you hopefully won’t be able to recognize by just a couple of words. You don’t even need to solve the plaintext, just tell me what is being discussed (i.e. the overall subject). Good luck. I’d be super impressed if you solve this.

Subject: game theory.
