Anyone still monitoring this thread?

Anyway, I brute-forced it and still did not find a solution. Hm?

I'm saying, e.g. for ciphertext 4, that there are 7! inner alphabets that will give the same solution.

BTW, in part 6 you say that more iterations don't increase security much. I would argue that for this cipher, they decrease security. With more iterations, the…

Why isn't this completely straightforward?

It's worse than that, because some parts of keys are irrelevant for short texts. E.g., with ciphertext 4, there are 7 letters in the inner alphabet that are un…

Hi, I'm looking for George Lasry. I am hoping to ask him about another cipher that is not on MTC3. Is he around?

Am I supposed to follow the route in the 3rd graphic file, and then fill in what I get into a new grid? If so, I am getting nonsense.
