¶ System
Index Entry
It is significant, however, that the angles surrounding a vertex cannot add up to 360⁰, for it is a condition of a system that it be finite; which is to say that it should curve back on itself from all directions. If the angles around any vertex add up to 360⁰, they would initiate an infinite plane. And since a plane has infinite extension and does not close back on itself, this condition violates the requirement of finiteness-- the essential property of a system.
