#Life 1.05 #R 34678/3678 #D This is a period 256 rocket gun which demonstrates the symmetry of the #D Day/Night rules, and how a signal can be sent across the border between #D day and night regions. Here a period 256 anti-gun destroys every other #D rocket from a normal period 128 rocket gun. Based on a reaction by #D Dean Hickerson. #D David I.
