		3	#D This is a finite version of the infinite p2 oscillator in which
		4	#D rows alternate full, full, empty, empty, full, full, ... Two types
		5	#D of edges are shown, one perpendicular to the rows and one at a 45
		6	#D degree angle. (It's easy to prove that there's no p2 edge parallel
		7	#D to the rows.) Also shown are 3 type of corners where the edges
		8	#D meet. This partly answers a question of John Conway's: What's the
		9	#D maximum average density of an infinite p2 pattern, and can it be
		10	#D obtained as a limit of finite p2 patterns? This shows that 1/2 is
		11	#D a lower bound. Hartmut Holzwart showed that 8/13 is an upper bound.
