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.
