Tub test tube baby is a period-2 oscillator. It is similar to test tube baby, but tubs are used to stabilizes the corners.


Tub test tube baby is about the twenty-ninth most common naturally-occurring oscillator in Achim Flammenkamp's census, being less common than the tumbler and more common than trans-beacon on dock.[1] It is the 29th most common oscillator on Adam P. Goucher's Catagolue. There are about four regular test tube babies for every three tub test tube babies.

Glider synthesis

All strict still lifes with a population of 20 or fewer cells, as well as all oscillators and spaceships with 16 or fewer cells, are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
