Period-20 glider gun is a true period-20 glider gun that was discovered by Matthias Merzenich in 2013 and improved by Karel Suhajda[1], based on Elkies' true period 24 gun. This is the shortest-period true-period gun known so far.
Filtering the output of the gun with a blocker yields the smallest known period-40 glider gun, beating the eponymous period-40 glider gun at its own game. The further addition of Rich's p16 doubles the period again, resulting in the smallest known period-80 gun, and adding 68P32.1 on top of that doubles the period once more to 160.
