'''Puffer 2''' was the second [[puffer]] to be found and was discovered by [[:Category:Patterns found by Bill Gosper|Bill Gosper]]. It is extremely [[dirty]] and its tail does not stabilize until [[generation]] 5533, after which it stays at [[period]] 140. It consists of a [[B-heptomino]] (shown here one generation before its standard form) escorted by two [[lightweight spaceship]]s. Its debris can be stabilized by a third lightweight spaceship as in [[ecologist]]. A [[pulsar]] is formed at the south-western side in generation 4957.

AlexanderVB: Added the temporarily-formed lightweight spaceship

'''Jaydot''' is a 9-cell methuselah with a lifespan of 6929 generations. The ratio of its lifespan to the number of cells in its bounding box is unusually high for a methuselah, though [[Bunnies 11]] is superior in that respect. Because the pattern is composed of common spark and a [[Prepond|common pond predecessor]], it is simple to synthesize.

==Stable pattern==
The stable pattern that results from jaydot has 1124 [[Cell|cells]] and covers an area of 259 by 214 cells; it consists of 68 [[Block|blocks]] (including one [[blockade]]), 66 [[Blinker|blinkers]] (including five [[Traffic light|traffic lights]] and three halves of an [[interchange]]), 50 [[Beehive|beehives]] (including two [[Honey farm|honey farms]]), 26 [[Glider|gliders]], 13 [[Loaf|loaves]], nine [[Boat|boats]], five [[Ship|ships]], five [[Tub|tubs]], one [[pond]], one [[toad]], and two [[Ship-tie|ship-ties]] in the form of a [[fleet]]. A [[lightweight spaceship]] is temporarily formed at the north-east side in generation 5416, but does not survive after generation 5453.

'''Acorn''' is a [[methuselah]] found by [[:Category:Patterns found by Charles Corderman|Charles Corderman]]. It was discovered no later than [[:Category:Patterns found in 1971|1971]]<ref name=Lifeline2>[[Lifeline Volume 2]], p. 6</ref>, though its exact year of discovery is unknown. Its maximum population, 1057, occurs in generation 4408.<ref name=Lifeline3>[[Lifeline Volume 3]], p. 12</ref> Also, it is composed of 2 or 3 sparks, depending on how the left side is looked at. Despite this, 4 gliders are required for synthesis. The left spark can be flipped to create another "isomer," that evolves the same way.

==Stable pattern==
The stable pattern that results from the acorn has 633 [[cell]]s and covers an area of 215 by 168 cells; it consists of 41 [[blinker]]s (including four [[traffic light]]s), 34 [[block]]s, 30 [[beehive]]s (including one [[honey farm]]), 13 [[glider]]s, eight [[boat]]s, five [[loaf|loaves]], three [[ship]]s, two [[barge]]s, two [[pond]]s and a [[mango]].<ref>{{cite web|url=http://pentadecathlon.com/lifeNews/2005/02/new_methuselah_records.html |title=New Methuselah Records |author=Koenig, H. |date=February 21, 2005 |accessdate=January 24, 2009}}</ref> An [[eater 1]] is temporarily formed at the north side in generation 2661, but does not survive after generation 3925.

== Name ==
The name was coined by [[Robert Wainwright]] "after seeing its final [[census]]",<ref name=Lifeline2/> which he called "oak tree",<ref name=Lifeline3/> apparently alluding to the proverb "From little acorns mighty oaks do grow".

AlexanderVB: Added additional information about the naturally-formed lightweight spaceship

'''23334M''' is a [[methuselah]] with a lifespan of 23334 [[generation]]s that was found by [[:Category:Patterns found by Tomas Rokicki|Tomas Rokicki]] on February 20, [[:Category:Patterns found in 2005|2005]]. It is notable because it is one of very few patterns to naturally emit a [[lightweight spaceship]] during the course of its evolution. For this pattern, the lightweight spaceship is created on the west side at generation 13811, before it is partially disturbed by a nearby set of cells until generation 13814, in which it survived and starts to escape westwards.

[[Simon Ekström]] identified an 11-cell equivalent fitting in the same 5×8 bounding box on May 13, [[:Category:Patterns found in 2016|2016]].<ref name="post30945" />

==Stable pattern==
The stable pattern that results from 23334M has 2898 [[cell]]s and consists of 207 [[block]]s, 171 [[blinker]]s (including 14 [[traffic light]]s), 115 [[beehive]]s (including six [[honey farm]]s), 70 [[glider]]s, 32 [[loaf|loaves]], 23 [[boat]]s, seven [[tub]]s, six [[ship]]s, four [[pond]]s, two [[long boat]]s, two [[beacon]]s, one [[toad]], and one lightweight spaceship.<ref>{{cite web|url=http://pentadecathlon.com/lifeNews/2005/02/new_methuselah_records.html |title=New Methuselah Records |author=Koenig, H. |date=February 21, 2005 |accessdate=January 24, 2009}}</ref>
