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. In terms of its minimum population of 33 cells, it is the smallest known non-trivial period 12 oscillator, although the trivial mold on long hook eating tub contains only 24 cells.[3] It can also be extended as an agar.
