TODO - work in progress

This page is meant to collect the many factual observations people have made about the 340 cipher over the years.

• The paper the cipher is written on contains several Fifth Avenue watermarks (here's [1] glurk's animation to help you spot where they appear).
• The first 3 symbols of the 340 do not reappear soon. It starts with "HER", and H only appears 3 other times, E only appears 2 other times. (From Duman)
• In the third column, the 3 occurrences of the "R" symbol are evenly spaced, each separated by four rows. (From Wrench)
