Small lake is a 20-cell still life. It is similar in structure to lake 2, although it is not a true lake itself due to its four sides that are only a single cell in length.

Two closely related still lifes; the first one is four siamese hats.

In other rules

It occurs frequently in the Life-like cellular automaton B3/S235e, evolving from several precedessors of traffic lights.

gollark: Presumably the encoding pagers use is well-known/documented enough that someone implemented a software decoder.

gollark: That's an example of it, I guess? You turn... what is it again... 3 bits into 7 bits and can convert it back even if it's scrambled a bit.

gollark: I feed `multimon-ng` audio data from the `rtl_fm` program (which demoduldates FM from the RTL-SDR) and it decodes the POCSAG-whatever protocol(s) and outputs the text again.

gollark: "Encoding" is just converting the data into a different form in some way... in this case I guess the text on the pagers to POCSAG-something.

gollark: That's not what encoding means.
