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] based on a partial result by Aidan F. Pierce.[1] 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, the amount of phase offsets being unknown), with the one pictured having minimum population and bounding box. A 101-glider synthesis for one of these variants was posted by Goldtiger997 on December 29.[3]

David Hilbert was voted on the ConwayLife.com forums as Pattern of the Year 2019.[4]

Notes
