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.

Commonness

Information on this oscillator's commonness with respect to other naturally-occurring patterns is currently unknown.

LCM oscillators

The smallest known oscillator of period 228 is an LCM oscillator comprised of a pulsar quadrant and a p76 pi-heptomino shuttle.
