Abstract
Vector replacement rules allow formulation of the flowsnake plane-filling curve as a bijection 
and as a surjection 
. The 
-function visits double and triple points predicted by Netto's theorem. Triple points belong to a relatively simple set, while double points resist easy classification. This paper formulates and analyzes the -function. Methods applied to the flowsnake also apply to other plane-filling curves.
