Pond is an 8-cell still life discovered by the JHC group in 1970.[1] It is the sixth most common still life, being slightly less common than tub and more common than ship.[2] It is the smallest lake, followed by the 24-cell lake 2.
Prepond
The prepond is an predecessor of the pond. It is important because it makes about 54% of the ponds that doesn't appear in any other Life-like rules (because, for some reason, the Prepond only turns into a pond in the Game of Life, and dies out / turns into active debris at other rules).
It dies out at HighLife, which is the reason these 54% just aren't there, making the pond almost half as common.
