Reply To: Stuff to do while you wait (with a message from Harry added)
I think which indicator letter you use doesn’t actually matter, I started with trying that as well but you get equally good results by just using the same letter and looping 26 times. I think you will just get a reordering of the inner wheel for each choice of indicator letter. Although like you I am also stuck after #1. Perhaps the cheat is guessing parts of the plain text? Or maybe there is some clever way to factor the cipher that I haven’t thought of?
