Period-256 glider gun is a true period 256 four-barrelled glider gun found by David Buckingham on September 26, 1995,[1] serving as an early "teaser" before releasing his full Herschel technology. It uses four R64 conduits to make a Herschel loop, which used to be the second smallest in terms of bounding box until the discovery of R49.

Either eater 1s or snakes can be added as shown in the infobox, to suppress three of the glider streams so that only one stream escapes. This gun's p256 glider stream is well-suited for repeated reactions with receding Corderships, or for "Hashlife-friendly" signal circuitry.
