This is embarrasing, I too have not yet solved 8B.
The tips say: Factors are your friend!
I broke the text into blocks and encrypted each block separately. . .
The factors are 5, 7 and 41.
I have tried both a Normal Transposition and
a Columnar Transposition in the following ways
Write by Rows Read by Columns (normal way)
Write by Rows Read by Rows
Write by Columns Read by Rows
Write by Columns Read by Columns
Using 35 blocks of 41 letters
I have only been able to obtain the first 8 WORDS
Is this a new take on the transposition cipher Harry?
