Mold is a period-4 oscillator found by Achim Flammenkamp in 1988 ,[1] Dean Hickerson rediscovered it (and named it) in August 1989 . In terms of its minimum population of 12 cells mazing as the smallest period-4 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.
It emits dot sparks , which can support other patterns such as four molds hassling eight blocks , traffic circle and "butter".[2]
Construction Mold is known to be constructible with 5 gliders [3] Mark Niemiec's database .[4]

Occurrence 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 tie ship .[5] Catagolue , it is the most common period 4 oscillator, being more common than mazing .[6]
The first natural mold stator variant, cis-mold on dock , occurred in May 2015 .[7]
The octo3obj database contains one collision with a mold in the ash.[8] three-glider collisions in the octo3g database with a mold in the ash; both collisions converge to the same sequence before the mold forms.[9]
