Tanner's p46 is a period 46 oscillator that was found by Tanner Jacobi in 2017 involving a pi running a small conduit. Mark Niemiec posted a 19glider synthesis two hours after its discovery. Various guns can be constructed by combining two of the oscillators themselves, one of which produces middleweight spaceships without any gliders required.

Pattern collection

The LifeWiki contains one of the most comprehensive catalogues of patterns available on the internet. Within it you will find:


Did you know...

 ... that all strict still lifes up to and including 14 cells have been found by apgsearch in asymmetrical 16×16 soups?
 ... that c/2 orthogonal and c/4 diagonal are the only speeds of spaceships seen to emerge from asymmetric soups on Catagolue?
 ... that all currently known standard Herschel conduits produce the same Herschel greatgrandfather pattern, except for Fx158?
 ... that eater 1 is the smallest asymmetric still life?
 ... that in Life, no spaceship can exist with a speed of (m,n)c/x where (m+n)/x > 0.5?
 ... that even without using fixedcost reverse caber tosser technology, an Nbit strict still life – specifically, some length of long long (...) boat or barge – can be constructed for any odd integer N using no more than 39 gliders, and for any even integer N using no more than 38 gliders, using a temporary tubstretcher?
 ... that even without using fixedcost reverse caber tosser technology, an Nbit period2 oscillator can be constructed for any odd integer N using no more than 45 gliders, and for any even integer N using no more than 46 gliders, using a temporary tubstretcher?
 ... that it is currently an open question as to if there exists a periodic pattern whose only predecessors are its own evolutionary sequence?
 ... that it was proved in the early 1970s that reflectorless rotating oscillators exist in Life, but none were found until 2018 when Adam P. Goucher completed the 0E0P metacell?
 ... that there are currently known elementary spaceships with speeds c/7 and c/10 orthogonal, but none with c/8 or c/9?
