34P7 is a period-7 oscillator found by Charity Engine on August 2, 2022. It produces a similar spark to meatball, but has a smaller population. It is less robust than meatball; there are some situations where meatball works as a sparker but 34P7 does not.[which?]

The oscillators below are listed due to being the smallest known ones by population, while also satisfying the condition that at least one cell oscillates at the full period.
