Mold on fumarole is a period-20 oscillator composed of a mold and a fumarole. In terms of its 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.

gollark: * anyway

gollark: Top 10 in your year group would be... probably top 10%, but it's not like you can measure intelligence with much precision anywya.

gollark: ++tel unlink discord 348702212110680064

gollark: Anyway, bye!

gollark: Besides, it says that a link is established on the other end.
