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.
Use
Pulsar quadrant is used in the smallest known oscillator of period 228, with the other part being the p76 pi-heptomino shuttle.
