Nihonium[note 1] is a period-113 oscillator, found by Jeremy Tan on July 5, 2021.[note 2] It was the smallest known oscillator of its period until the discovery of 86P113 in October, 2022. It is an emu comprised of two R64 and two R49 conduits populated with two Herschels whose first natural gliders annihilate each other; both Herschels must be present for the oscillator to work, but one Herschel may be advanced in time to yield a period-226 oscillator, the least-populous of them at 107 cells called nihonium*.
A 52-glider synthesis was found for nihonium on the day of its discovery.
- ↑ Named after the element with atomic number 113, which in turn is named after Japan.
- ↑ An independent but incomplete attempt to construct a Herschel loop with two R49 and two R64 was made by PHPBB12345 dated back to 2019.
