Octagon 2 was the first known period 5 oscillator, discovered in 1971 independently by Sol Goodman and Arthur Taber; 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.[1] On Catagolue, it is the most common period 5 oscillator, being more common than fumarole.[2]
