Jam

Jam was found by Achim Flammenkamp in 1988,[1] but not widely known about until its independent discovery (and naming) by Dean Hickerson in September 1989. In terms of its 7×7 bounding box it ties with trice tongs as the smallest period-3 oscillator, though caterer has fewer cells.

Commonness

Jam is about the seventeenth most common naturally-occurring oscillator in Achim Flammenkamp's census, being slightly less common than the blocker.[2] On Catagolue, it is the second most common period 3 oscillator, being less common than the pulsar but more common than the candlefrobra on trans-block.[3]

gollark: Because I dislike it somewhat.
gollark: That looks like I'm upvoting it.
gollark: It means "triangular".
gollark: That too.
gollark: No, considered controversial or NSFW *by me*.
