Mold on pentadecathlon

Mold on pentadecathlon is a period-60 oscillator composed of a mold and a pentadecathlon. Although it is composed of two oscillators of smaller periods (4 and 15 respectively), it is considered non-trivial, because it has a single cell that is alive in generation 5 and is dead in the other 59 phases of the oscillator. In terms of its 24 cells it is the smallest known period 60 oscillator.

Generation 5 reveals the single cell that oscillates at the full period (in green).
gollark: I'm standing right next to it, but nothing happens when I do `modem.transmit(1, 0, "nanomachines", "setInput", [lots of numbers because it's in a for loop], true)`.
gollark: <@204906817816363009> I'm trying to use an OC relay controlled via CC.
gollark: Well, that too, but mostly nanomachines.
gollark: Can anyone help with accessing an OC relay via CC?
gollark: Degenerating into pointlessness much?
