i figured out what that symbol probably is during the course of something i'm currently working on. it's probably the tetractys:
https://en.wikipedia.org/wiki/Tetractys sacred symbol of the pythagorean brotherhood(500 B.C). it symbolises, more or less, totalitarian rationalism(fascist mathematics, or. . ."the science") as preached by plato in 'the republic' and adopted by aristocratic rationalists during renaissance, and then also the illuminati.
when depicted with the eye on the top of the pyramid instead of center, the eye = the monad. the monad- "the one", which is why they put it on the "one" dollar bill and put a big fucking "ONE" on it instead of using numerals like all the other bills - "ONE" "5" "10" "20" "50" 100""
