Maybe someone has already noticed this, but I share.

1)A little game with the z408,
In the case in a mirror version of the first part deciphered we can "find", perhaps, a quote to the famous and genius Edgar Allan Poe, who read The Gold Bug – https://en.wikipedia.org/wiki/The_Gold-Bug (and who has not read ?? !!) knows the link I make.

2) It should be noted that the cipher in the gold bug can be divided into 12 rows of 17 columns in length, ie half the z408 and contains 204 symbols which is exactly half the total length of the Z cipher.
Coincidence ?? !!
