Two pulsar quadrants is a period-3 oscillator that was found by David Buckingham in July 1973.[1]

A 10-glider synthesis of this oscillator was found by gmc_nxtman on July 12, 2017.[2] This was improved to 9 gliders by gooddogtyson on July 25, 2020.[3] On July 24, 2024, Carson Cheng lowered the cost to 8 gliders.[4][5]
