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]} based on a partial result by Aidan F. Pierce.^{[1]} It consists of two copies of an engine, itself consisting of a Bheptomino being hassled by two unusual catalysts and a block, supported by a known periodagnostic 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
