Trans-beacon on table (or down beacon on table) is a period-2 oscillator. A 5-glider synthesis of this oscillator was found in January 2020.[1]


Trans-beacon on table is about the twenty-second most common naturally-occurring oscillator in Achim Flammenkamp's census, being slightly less common than the cis-beacon on table but more common than Achim's p4.[2]
