Mold

Mold was found by Achim Flammenkamp in 1988,[1] 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".[2]

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.[3] On Catagolue, it is the most common period 4 oscillator, being more common than mazing.[4]

gollark: But we can convert you into arbitrary lizards, for purposes.
gollark: However, we reserve the right to convert you into lizards at any time.
gollark: Of course.
gollark: I have to use a small model due to VRAM constraints so it MAY not be very good.
gollark: This is in progress.
