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 praosylen.[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), 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]
Other p23 oscillators can be constructed that combine David Hilbert with the p23 honey farm hassler.[4]
David Hilbert was voted Pattern of the Year for 2019 on the ConwayLife.com forums.[5]
