Octagon 2 was the first known period-5 oscillator, discovered in 1971 independently by Sol Goodman and Arthur Taber;[1] the name is due to the latter. Its discovery was first reported in Lifeline Volume 1.

Commonness

Octagon 2 is about the twenty-sixth most common naturally-occurring oscillator in Achim Flammenkamp's census, being about as common as unix.[2] On Catagolue, it is the most common period 5 oscillator, being more common than fumarole.[3]
