26. OK. Squares or rectangles, so what’s the big deal?
Now you’re talking. Unlike the formation of ST on nothing but simple circle/square geometry, asymmetrical rectangles allow for specific, slightly different geometry to come into play—within the ISL layout—at articulated points of interest—nodes—that give the forming ST new instructions, e.i., at this nodal point of ST formation, your next expansion shall now follow the rectangular geometry of the PT versus the circle/square geometry of the strict ISL.
