The statorless p6 is a period-6 oscillator discovered by Dean Hickerson in August 1989.[1] It is one of the few known period 6 oscillators without a stator, giving it a volatility of exactly 1.
Strictly volatile variant
Additionally, a variant of this oscillator exists which is strictly volatile (i.e. all cells oscillate with period 6 rather than period 2 or period 3). A 30-glider synthesis for said variant was found on October 4, 2019 based on a soup submitted to Catagolue,[2] and was reduced to 28 gliders by an anonymous user on February 5, 2022.[3][4]

Other statorless p6
Another occurred semi-naturally in two soups submitted within an hour of each other by Charity Engine on 2022-03-04, comprised of entirely different mechanisms, though it isn't strictly volatile due to its central cells oscillating with period 3.
