Beluchenko's p51 (or 112P51) is a period-51 oscillator that was discovered by Nicolay Beluchenko on February 17, 2009.[1] It was the first non-trivial period 51 oscillator to be found, all previously known period 51 oscillators being made up of disjoint period 3 and period 17 oscillators. It can be extended diagonally by making copies of itself share two blocks as shown below.

A 76-glider synthesis of this oscillator was found by Jason Summers and Matthias Merzenich in April 2010.[2] This was improved to 43 gliders by Chris Cain on January 5, 2020.[3]
