Test tube baby

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]

Commonness

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.[2]

It is the most common billiard table naturally, depending on the definition of billiard table.
