I never really looked into the 741 stuff too much, but I recall that Cohen repeated a 741 sequence in different ways. For example 7 tweets one month, 4 the next, then 1 then next. Then repeat. There were others, like him taking a selfie at a GameStop store with the items in background arranged in 741 formation.

There have been many instances with 741 potentially tying-in, like the VW/Porsche short squeeze.
