Jam was found by Achim Flammenkamp in 1988, 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.[1]
