He's talking about the 3,142 interpratation for the 4 pictograms.
Anyway I'm not convinced about both main interpratations: both the binary and the Pi ones, still have some flaws.
There's no need of Pi, to make a circle from the drawing.
Pi depicted with human numbers does not attract me too much.
The two top glyphs are different from the bottom's, whatever anyone can say about it. They are.
What I think is that we are still missing their real meaning.
The only one explaination that I'm still keeping, not because it's mine

, is the good correlation between the hi/low purrs in the UP transmission, and the four glyphs on the drawing.
The reason why I LIKE it so much, is that it does not need any numbers or human conventions at all, assuming the glyphs being just PLACEHOLDERS for the four quadrants, and each triplet in the transmission recalling one of the glyphs, and then one of the quadrants. What we can do with a sequence of quadrants is still unknown.
Anyway, also this theory is far from being perfect. Very far. Too much.
