122P23 (or David Hilbert[1][note 1]) was the first period-23 oscillator to be discovered. It was found by Luka Okanishi on November 24, 2019.[2] It consists of two copies of an engine, itself consisting of a B-heptomino being hassled by two unusual catalysts and a block, supported by a known period-agnostic beehive shuttle mechanism (seen in, for example, an extension of the carnival shuttle). There are several isomers known (including trans- versions and different phase offsets), with the one pictured having minimum population and bounding box.
Notes
