A period-256 glider gun is any glider gun with true period 256.
A true period-256 four-barrelled glider gun was found by David Buckingham on September 26, 1995, 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.

The left one (Catagolue: here) was found by Buckingham before November 1991, which can be modified to a Herschel factory.[1] The right one (Catagolue: here) is an unsuccessful attempt to make a p64 oscillator.[2] (click above to open LifeViewer) RLE: here Plaintext: here |
