Test tube baby is a period-2 oscillator, being the smallest oscillator to support the two-cell domino rotor. It and its variants are occasionally considered to be billiard tables.[1]
Uses
The test tube baby is sometimes used when two eater 1s need to be placed close together; the eating mechanism works identically, regardless of the phase of the oscillator.[2]
Occurrence
- See also: List of common oscillators
Test tube baby is about the twenty-fifth most common naturally-occurring oscillator in Achim Flammenkamp's census, being less common than cis-beacon on anvil and more common than octagon 2.[3] It is the 24th most common oscillator on Adam P. Goucher's Catagolue.
It is the most common billiard table naturally, depending on the definition of billiard table.
Glider synthesis
A 5-glider synthesis of this oscillator was found and submitted to Catagolue by Carson Cheng[4] in March 2022.[5]
