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 A capped version of this gun was the smallest known period-246 oscillator by population until it was superseded by unix on p82 lumps of muck hassler.

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