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. It is about the twenty-sixth most common naturally-occurring oscillator, being about as common as unix.[1]
