Beluchenko's p37, also called 124P37, is a period-37 oscillator consisting of 4 loafs 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. 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.
