Beluchenko's p51, also known as 112P51, is a large, symmetric period51 oscillator found by Nicolay Beluchenko in 2009, being the first nontrivial oscillator of its period to be found. It can be extended diagonally by making copies of itself share two blocks.

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 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?
 ... that there are currently known elementary spaceships with speeds c/7 and c/12 diagonal, but none with c/8, c/9, c/10 or c/11?
 ... that while the speed limit for orthogonal spaceships in rules using the Moore neighbourhood is c orthogonal, spaceships in Larger than Life rules are capable of breaking this barrier?
 ... that without the use of adjustable glider loops, there are no known oscillators with periods 43 or 53?
 ... that without the use of Herschel loops or adjustable glider loops, there are no known oscillators with periods 59 or 61?
 ... that small stable elementary period multipliers (also known as pulse dividers) have been found for multipliers of 2x, 3x, and 4x, but not for 5x or higher?
 ... that with reverse cabertosser universal constructor technology, it is possible to build any possible gliderconstructible pattern, no matter what size, using only 35 gliders?
 ... that there are at least four known ways to send information diagonally at a speed greater than the maximum spaceship speed through vacuum? (Complete mechanisms include speeds approaching c/2 via two perpendicular telegraphs, and 2c/3 via a 2c/3 wire.)
 ... that an oscillator with strict volatility 1 can be constructed for any period 3506909 or higher?
