The quadpole (or tetrapole) is the barberpole of length 4.

Commonness

The quadpole is the eighth most common oscillator in Achim Flammenkamp's census, being less common than the bipole but more common than the great on-off.[1] Despite behaving the same in Life as they do in HighLife, they are only about 2% as common.

gollark: Which is part of the dev server, yes.

gollark: Where did you THINK they developed SwitchCraft? Not a dev server?

gollark: Besides, the security system was shooting holes in the walls.

gollark: Fire resistance doesn't actually stop laser damage.

gollark: That's labeled as secret so you can't see it.
