Test tube baby is a period 2 oscillator, being the smallest oscillator to support the two-cell domino rotor.


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.[1]

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