Revision as of 08:32, 17 October 2023 by Confocal(talk | contribs)(LoafRock: Rock lying 3 mi W of Biscoe Point, off the SW coast of Anvers Island in the Palmer Archipelago. Surveyed by the British Naval Hydrographic Survey Unit in 1956-57. So named by the UK Antarctic Place-names Committee (UK-APC) in 1958 because the rock is shaped like a flat loaf of bread. https://web.archive.org/web/20210602222037/https://geonames.usgs.gov/apex/f?p=gnispq:5:::NO::P5_ANTAR_ID:8947)
Beluchenko's p37 (124P37) is a period-37oscillator consisting of 4 rockloaves 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 and was one of only two known before the discovery of 58P37 in 2022. In terms of its 124 cells, it was also formerly the 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.
This oscillator first appeared on Catagolue in March 2015.[2]
About 1 in 7.6 billion eightfold symmetric soups with odd symmetry (D8_1) form a Beluchenko's p37. About 60% of them form as shown in the infobox, while almost all the rest form with ponds instead of loaves.
