So here’s the third method I’ve heard of for solving K3: a double rotational transposition.
As always, the easy visualization/manipulation site:

Leave off the ? and grid it into a 24×14 grid. Rotate to the right 90 degrees.

Once again this involves leaving the ? behind but can we say that’s proof to leave it with K4?
2 out 3 methods leave it out however those methods require a grid that presupposes the ? must be left out.
The Q is in for sure however.
So how does this compare to solution 1 and solution 2? Man, if I knew that I’d probably have the brain power to solve K4 by now.
It’s all just reversing the original transposition. I’m sure computer analysis could follow each letter as it makes the adjustments for each method and calculate the vectors needed. After that it could extrapolate all the possible algorithms to result in plaintext recovery from K3′s ciphertext.
For the rest of us, we know that it works and that’s great.
3 separate but related methods of solving K3.
I bet this is the real method.
Shouldn’t the ? be included?
Technically arent they all 3 doing the same thing? You’re just cutting the 192 up into several steps. I like it though.
