Achim's p8

Achim's p8 is a period-8 oscillator discovered by Achim Flammenkamp on July 20, 1994.[1] In August 2004 Jason Summers and Mark Niemiec found a 13-glider synthesis of this oscillator.[2]

Commonness

On Catagolue, it is the fifth most common period 8 oscillator, being slightly less common than smiley but more common than blocker on cis-dock.[3] It first occurred naturally on August 21, 2015, in a soup submitted to Catagolue by Tanner Jacobi.[4]

gollark: Going on about "the common source", "yin and yang" and "the dao" seems, well, pretty religion-like.
gollark: I too love pattern-matching hypothetical physicsy things to strange religious beliefs.
gollark: What's your evidence for there being multiple universes? Also stuff outside it. I don't think you can observe any of that.
gollark: Even really weird esoteric maths with no apparent practical applications sometimes turns out to be very useful somewhere.
gollark: 5G is very overhyped.
