TetraPheric

6.1 "It takes a minimum of six interweaving trajectories to isolate insideness from outsideness, ergo, to divide all Universe systematically into two parts

-- macrocosm and microcosm." (I, 240.32)

6.2 "A system is the first subdivision of Universe. It divides all the Universe into six parts:

first, all the universal events occurring geometrically outside the systems
second, all the universal events occurring geometrically inside the system:
third, all the universal events occurring nonsimultaneously. remotely, and unrelatedly prior to the system events;
fourth, the Universe events occurring nonsimultaneously, remotely, and
unrelatedly subsequent to the system events;
fifth, all the geometrically arrayed set of events constituting the system itself; and
sixth, all the Universe events occurring synchronously and or coincidentally to and with the systematic set of events uniquely considered."(I. 400.011)
