'''Anvil''' is an [[induction coil]]. After 42 generations, it stabilizes into a period 2 [[blinker]]s and a [[block]].

'''Seeds''' is a life-like [[cellular automaton]] in which only dead cells with exactly two live neighbors will turn into live cells on the next generation. Even though all the living cells die in every generation (turning every pattern into a [[phoenix]]), most patterns are still exploding quadratically.

==Notable patterns==

===Oscillators===
It is obvious that no [[still life]]s can exist in this rule. Known [[oscillator]] [[period]]s include 2, 3, 4, and 6. The five smallest ones are [[duoplet]] (2 cells, p2), shiplet (3 cells, p2), radar (4 cells, p4), lever (4 cells, p4) and anchor (4 cells, p4).


===Spaceships===
With B2, the Seeds rule allows [[spaceship]]s to travel at the [[speed of light]]. The three smallest ones, known as [[photon]]s, have a period of 1 and consist of only 4 cells each. Larger lightspeed spaceships with higher periods are also known.

There also exist c/2 and c/5 orthogonal spaceships and c/3 and c/4 diagonal spaceships.

===Guns===
Two period-4 photon [[gun]]s ([[laser]]s) have been found, yet their photon stream is too dense to implement any [[signal logic]].

===Puffers, Rakes and Breeders===
Quite a lot of progress has been made in producing engineered patterns consisting of lightspeed [[puffer]]s and photon [[rake]]s. A rake puffer [[breeder]] is known.

'''Eater siamese eater''' (or '''eater with nine''') is a [[still life]] consisting of two [[eater 1|eater]]s [[Siamese|attached]] to each other. As a result it can eat gliders, too.

Three other ways of [[Siamese|siamizing]] two eaters together are possible. The first two are similar 12-cell objects, while the third — [[elevener]] — is a deeper connection.

==[[List of common still lifes|Commonness]]==
Eater siamese eater is the fifty-eighth most common [[still life]] in [[Achim Flammenkamp's census]], being less common than [[cis-boat and dock]] but more common than [[cis-block and long hook]].<ref>{{citeAchim|accessdate=January 15, 2009}}</ref> It is also the sixty-eighth most common object on [[Adam P. Goucher]]'s [[Catagolue]].<ref>{{citeCatagolueStats|June 24, 2016}}</ref>

The '''pseudo-barberpole''' (or '''Achim's p5''') is a [[period]] [[:Category:Oscillators with period 5|5]] [[oscillator]] that was found by [[:Category:Patterns found by Achim Flammenkamp|Achim Flammenkamp]] on August 22, [[:Category:Patterns found in 1994|1994]].<ref name="hickerson" /> With a minimum population of [[:Category:Patterns with 15 cells|15]] [[cell]]s, it is the smallest known period 5 oscillator, followed by [[octagon 2]] with [[:Category:Patterns with 16 cells|16]] cells.<ref name="niemiec_p5osc" /><ref name="pentadecathlon_class2" /> On October 23, [[:Category:patterns found in 2002|2002]] [[Gabriel Nivasch]] found a period 5 oscillator that consists of four radially symmetrically arranged halves of the pseudo-barberpole.<ref name="summers_all-osc" />
