Mold on fumarole is a period-20 oscillator composed of a mold and a fumarole. In terms of its minimum population of 30 cells, it is the smallest known period 20 oscillator.[1]
Despite being composed of two oscillators of smaller period (4 and 5 respectively), it is considered non-trivial because it has a single cell that is alive in generation 1 and is dead in its other 19 phases.
