Commonness
The pond is the sixth most common still life in Achim Flammenkamp's census, being slightly less common than tub and more common than ship.[2] It is also the nineth most common object on Adam P. Goucher's Catagolue.[3]
Prepond

The Prepond.
The prepond is a common predecessor of the pond. The prepond turns into a pond in 32 Life-like rules, from B3/S23 to B378/S23678, but it dies out in HighLife. Consequently, the pond occurs more than twice as commonly in Game of Life than in HighLife.

gollark: Idea: buy cheap computronbox™, install Windows (!!!!!!!!!!!!!!!!!!), isolate on very isolated network, use RDP to access it.
gollark: Testbot responds to "testbot, bees" and stuff.
gollark: The issue is that the bridge says "<Heavpoot> whatever" on the other side.
