Reply To: Challenge 10B
Regarding my attempt at solving 10B as a 16×36 grid – I think I have gone as far as I can and am left with 5 letters that don’t match the plaintext and I cannot fix without using patterns in the key or if I referred to the plaintext (99.85% solved). The key pair I ended up with is:
KEY1 =

The methods I used would have worked if the plaintext had been longer, but with the plaintext being less than three times the length of the total key length it was always going to be questionable as to whether a full solution would be possible limited by the strict criteria I had set myself.
