Nihonium[note 1] is the smallest known period-113 oscillator, found by Jeremy Tan on July 5, 2021.[1][note 2] 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.[3]

Notes
- ↑ 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 forums user PHPBB12345 dated back to 2019.[2]
