Dinner table is a period-12 oscillator. It was the first period 12 oscillator to be found, and was discovered by Robert Wainwright in 1972.[1][2] It consists of four eater 1s hassling a pre-beehive.

Generation 1 reveals that the object being hassled is a pre-beehive

In terms of its minimum population of 33 cells, it was the smallest known non-trivial period 12 oscillator until the discovery of the 31-cell mold on fire-spitting.[3]

It can also be extended as an agar.

Glider synthesis

On September 24, 2021, Aleph posted a final step for a synthesis,[4] which iNoMed used to complete a 58-glider synthesis.[5] Shortly after, Kazyan reduced the cost down to 19 gliders.[5] On July 28, 2024, Carson Cheng lowered the cost to 18 gliders.[6][7]
