Pulsar is a large but surprisingly common period 3 oscillator. Itwas found very early on by John Conway.

The rotor of a pulsar consists of four mutually stabilizing quadrants; alternate arrangements exist for any odd multiple of 4 (for the version with 12 copies, see quasar). A closely related oscillator — the pulsar quadrant — includes just the external "horns" of the rotor and can be stabilized on its own.

Commonness

Despite its size, pulsar is the fourth most common oscillator (and by far the most common of period greater than 2) in Achim Flammenkamp's census; the only oscillators more common are blinker, toad, and beacon.[1]
