Can it also tell us whether grid is special, vs it just being 340 sequential characters like 408? What I mean is, does the shape of the "26 L=17&…
I wonder if we are talking about columnar transposition or columnar rearrangement? (I think) I am thinking about columnar rearrangement. With 17! per…
The 26 L = 17 observation is very interesting to me […] I’m going to have to have a chew on all this. I know it’s a simple thing, but that first ch…
… the best way to defeat this weakness is to do a columnar transposition. This way you can separate the double letters that created the bigram, and …
(I only joined the forum last week, so I’m not the most experienced to answer but my opinion is..) Period 19 is a very simple transformation, resulti…
You might want to do this "properly" – I’ve done this by hand in a spread sheet, so may contain errors. This grid is an overlay for the 340…
I find the distribution of non-repeating sequence lengths (from David Oranchak’s ACA Presentation Video 38:31 – Sorry, I don’t know the source for thi…
Quick example: 221 character plain text encoded to 43 symbols, then added 20 null symbols: Solved in under a minute with standard 5-grams so more nu…
It’s so difficult to create mathematical random by hand that it probably doesn’t matter too much knowing the goal in advance. So the hypothesis would…
What sort of research has been done already regarding cipher symbols mapping to pairs of letters such as digraphs, like one symbol meaning "ee&qu…
63 symbols vs the 408’s 54 The assumption being that ALL the extra 9 symbols over the 408’s 54 were nulls. I figured that if there were a few more o…
Since I’m putting all my unhelpful stuff in this threat… I’m aware that it’s very difficult for a human to create a truly random pattern if they try….
I can see how quickly this can become disheartening. (Before reading your post above) I ran some quick null experiments on my PC. On the hypothesis …
I do agree. I guess it’s that middle ground between spotting a pattern that is so common it is almost definitely a coincidence, and something so rare…
Ah well, at least it has been explored. I can see its going to be a bit of a problem knowing what things have been tried already, as a newcomer to th…
