Beluchenko's p37 is a period-37 oscillator consisting of 4 loaves and 8 blocks hassling 8 R-pentominoes. It was the first period 37 oscillator to be found, and was discovered by Nicolay Beluchenko on April 14, 2009.[1] It was the only known unique period 37 oscillator until the discovery of 132P37 in March 2010. In terms of its 124 cells, it currently smallest known period 37 oscillator. Adam P. Goucher noticed that two of these oscillators could interact non-trivially by hassling a beehive and a block.

Matthias Merzenich found a 76-glider synthesis for this oscillator on July 12, 2009,[2] and improved it to 72 on September 9, 2013.[3]

This oscillator first appeared on Catagolue in March 2015.[4]
