Pond is an 8-cell still life discovered by the JHC group in 1970. It is the smallest lake, followed by the 24-cell lake 2.
It can be seen as a photonegative block.
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. It is also the nineth most common object on Adam P. Goucher's Catagolue.
The prepond is a common predecessor of the pond. It is important because it makes about 54% of ponds. 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.
