Period-246 glider gun is a true period glider gun with period 246, discovered by Dave Buckingham in June 1996.[1] The 180-degree mod-123 symmetry of its bookend-based engine makes it trivial to modify it into a double-barrelled gun. A capped version of this gun was the smallest known period-246 oscillator by population until it was superseded by unix on p82 lumps of muck hassler (Catagolue: here).

Upon the discovery of R49, praosylen noted that the same stable catalyst can also support the inactive part of the gun.[2]
