What if there are three?

I think it will follow the logic of most other binary things - it will alternate. What I mean is this: assume that during a single swing (no return), a pendulum going left-to-right is 1 and a pendulum going right-to-left is -1. With two, the sequence is {1, -1}. Three, it is {1, -1, 1}. And so on. They would always go opposite of their immediate neighbours, assuming that they are closer to some than others - with three in an equilateral triangle, I would say either they would sync at a 120 phase, or completely wreck their inner sync and eventually cause them to stop.
