Above is a period-754 glider gun based on the stable reflector. Note that all periods 754+8n (n>0) can be realized simply by moving the reflectors farther apart. Periods 749+4n can also be realized by placing two gliders on the path at the same time. Other kinds of guns can be made by choosing a different glider to recirculate. Any sufficiently high period oscillator can be realized by recirculating gliders through a path of such reflectors and using eaters to eliminate excess gliders.
