Pulsar is, despite its size, the fourth most common oscillator (and by far the most common of period greater than 2). The three more common oscillators are blinker, toad, and beacon.[1] Pulsar was 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.
