Re: Construction Challenges and Ideas

A constellation of still life that will reflect a glider and use universal construction to make a copy of the constellation displaced by an adjustable offset somewhere else and destroy the original constellation. So a one time reflector that after reflecting is displaced by a preprogramed in amount.

I can't find anything but p2 oscillators.
All patterns I have tried either die or become p2.
Are there any other periods know in B345678/S?
Is there someway to prove every pattern in this rule is p2?
