Period-46 glider gun
- This article is about period-46 guns as a general concept. For specific guns with period 46, see p46 gun (disambiguation).
A period-46 glider gun is a glider gun which has true-period 46. The first one found was the new gun by Bill Gosper in 1971. Prior to the discovery of Tanner's p46 in October 2017, all known p46 guns were made from two or more twin bees shuttles that interact (e.g., see twin bees shuttle pair). See edge shooter and double-barrelled for two more of these.
On 21 October 2017 Heinrich Koenig found the glider gun shown below, which uses two copies of Tanner's p46 placed at right angles to each other. This is the first p46 gun found which makes no use of the twin bees shuttle.[1]

See gliderless for a LWSS gun made of 3 copies of Tanner's p46.
On May 2, 2022 iNoMed found a period-46 gun that uses an engine unrelated to the twin bees shuttle or Tanner's p46.[2]
