Okay, after some calculations there are 1410877440 possible keys that can still produce valid arrangements for the transposition key. However, just a bit more than 1 gives the bigram count we need [less that 27] for the correct solution. I’ve found this number through this code:

Then I coded a script to go through every key for Tabular Transposition (I won’t reveal it yet, but don’t threat it still doesn’t work), turned each chain of three into a number 1-6 and checked that the total number of bigrams (e.g. AX, DV, FX…) was less than 27. So far absolutely nothing, and I’ve only gotten 50762 keys into that massive number.

Am I on the right track? Or am I just blind to the answer that has been staring me in the face since last year?

It is a great idea, but I think you are not making the most of the brick clues! (Sorry we mostly don’t post code so we don’t end up with everyone copying everyone else without writing their own. In this case we very much do like competitors (re)inventing the wheel for themselves! Harry
