Re: Rules with small adjustable spaceships

A rule which has adjustable ships for all speeds c/n for n>8. I think the first rule of this kind. Maybe there is a relative rule (keeping the three reflecting elements) which allows for all c/n speeds. however c/2 seems to be tricky. x = 204, y = 92, rule = B2akn3cn4ijnrw5cij6a8/S1c2-ak3ceiy4acenw5...
