Beluchenko's p51 or 112P51 is a period-51 oscillator that was discovered by Nicolay Beluchenko on February 17, 2009. 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.
