Coe's p8 is a period-8 oscillator that was found by Tim Coe on August 19, 1997.[1] It is about the forty-seventh most common naturally-occurring oscillator.[2] In terms of its 17 cells, it is tied with smiley as third-smallest known period-8 oscillator.

In August, 2004 Mark Niemiec found a 16-glider synthesis of this oscillator.[3] In October, 2010 Martin Grant found an 8-glider synthesis, based on a predecessor discovered by Lewis Patterson.[4]
