I'm not sure why my head keeps returning to this idea posted on the old message board but it woke me from a sound sleep. I still think it's one of the best non-technical cipher observations I've seen. I know not everyone is into reading cipher threads but I think it deserves more attention than it got the first time around.

Jem's observation was that the 340 and 408 ciphers combined would fit precisely onto two full pieces of standard graph paper. A 1/2 inch ruled piece of 8 1/2 X 11 graph paper yields a 17 X 22 grid or 374 spaces. Two pages= 748 spaces, which is the combined capacity of both our solved 408 cipher and unsolved 340 cipher.
Coincidence or POSSIBLY an indication that the two ciphers were created at the same time?
Does this lend any creedence to the possibility that the 340 cipher could be a continuation (differently encoded) of the 408 or that the unsolved portion of the 408 cipher might represent the beginning of the 340?
Perhaps a mod could bring the original discussion over here?
