Pulsar quadrant (or pulse) is a period-3 oscillator that was found by David Buckingham in July 1973.[1] It consists of a quarter of the outer part of a pulsar stabilized by a cis-fuse with two tails.
Information on this oscillator's commonness with respect to other naturally-occurring patterns is currently unknown.
All strict still lifes with a population of 23 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 35 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
