If the two sombreros are moved three spaces closer to one another then the oscillator's period drops to 4, and the result is just a less compact form of Achim's p4.

If the sombreros are moved 3 cells closer together, a period 4 oscillator results
gollark: I cannot be stopped.
gollark: False, I AM currently processing electromagnetic radiation into qualia.
gollark: I see.
gollark: As you can clearly tell, it is wrong.
gollark: This is an analysis of your disagreement.
