Period-92 glider gun is a glider gun with a true period of 92. The first one was found by Bill Gosper in 1971 using a period doubling reaction between two p46 guns. Many different p92 guns are known that use multiple twin bees shuttles. A period 92 gun can also be made by adding a semi-cenark or semi-Snark to any period 46 glider gun.
On 18 November 2017, Martin Grant found a new gun using one twin bees shuttle and one Tanner's p46 oscillator, making it the smallest known p92 gun.
