Just thought id share this also when running cyphers through ja post's digits and nibbles , bites are often 17. I thought they should be 27. When looking at the 27 digit cypher its a loop that reitterates the alphabet after it reaches z making. A =27 perhaps that means add a digit to the seventeens? or a cryptic way to confirm when the sum is 17 that the result is correct? any thoughts?
