The Naibbe cipher

[ololololo]

At bottom, the big statistical limitation of the original Naibbe cipher is that each draw of a word (when encrypting standalone letters) or of a prefix/suffix (when encrypting letter pairs) is memoryless and independent.

I believe the reason for this is that Naibbe is based on the principle of substitution. A simple replacement of letters with vords...
I have a very poor understanding of your works. @magnesium, as I haven’t bothered to read them, so I’ll ask a somewhat strange question — what changes to the Naibbe cipher make it closer to VMS statistics? I.e., what needs to be done in an unintended way to make it even better (preferably without introducing rules based on the VMS text)?
