Coe's p8 is a period-8 oscillator that was found by Tim Coe on August 19, 1997.[1] In terms of its 17 cells, it is tied with smiley as third-smallest known period-8 oscillator. It consists of two blocks hassling an unnamed object, similar to blocker. The unnamed object is a hive predecessor that looks like two linked gliders. The spark created by the block eating can support the bumper, but the blocker would be smaller for that purpose.

Commonness

Coe's p8 is about the forty-seventh most common naturally-occurring oscillator in Achim Flammenkamp's census.[2] On Catagolue, it is the third most common period 8 oscillator, being less common than the blocker but more common than smiley.[3]

Synthesis

In August, 2004 Mark Niemiec found a 16-glider synthesis of this oscillator.[4] In October, 2010 Martin Grant and Matthias Merzenich found an 8-glider synthesis, based on a predecessor discovered by Lewis Patterson.[5] The best synthesis known as of July 2017 uses 5 gliders and was found by gmc_nxtman and Mark Niemiec on July 8, 2017.[6]
