Mold was found by Achim Flammenkamp in 1988, but not widely known until Dean Hickerson rediscovered it (and named it) in August 1989; compare with jam. In terms of its minimum population of 12 it ties with mazing as the smallest period 4 oscillator, but in terms of its 6×6 bounding box it wins outright. In fact, of all oscillators that fit in a 6×7 box it is the only one with period greater than 2. Its spark can support other patterns, such as "Butter".[1]

It has a similar rotor to mazing.

Commonness

Mold is the twelfth most common naturally-occurring oscillator in Achim Flammenkamp's census, being less common than the spark coil but more common than the quadpole on ship.[2] On Catagolue, it is the most common period 4 oscillator, being more common than mazing.[3]
