Ok, I'm pretty sure I've decoded the data successfully. But now I'm not sure what to do with the result--maybe I'm just seeing too many different possible patterns.
I already know it's not the number that relates all the rows together (though judging from the hints it's significant).
I'm trying to make sense of how to use the symbols. I've tried a variety of things including ASCII art. So far no luck.
Thanks for any help.
