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.

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]

All strict still lifes with a population of 23 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 35 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
