P18 bi-block hassler (or 43P18) is a period-18 oscillator discovered by Noam Elkies on February 20, 1995.[1] In terms of its 43 cells, it is the smallest known period 18 oscillator.[2][3] The unix on the bottom can be positioned in 2 places.

It is composed of two copies of unix that are hassling a bi-block, as shown below.

Generation 14 reveals that the oscillator is made up of two copies of unix and a bi-block.

gollark: Actually just do `pip install --user https://github.com/drathier/stack-overflow-import/archive/master.zip`.

gollark: git clone it, then just do stuff in the directory you get?

gollark: Or specify challenges in more detail?

gollark: Is there a way to chain together the results you get?

gollark: Well, it's an interesting idea, but it sounds like it would run slowly.
