I found a simple Hershel reaction that can move a block by (3,0)!calcyman wrote:That's the most promising result. It's a shame that the block is displaced by (3,0).
Code: Select all
x = 9, y = 12, rule = B3/S23

A simple Herschel conduit should be able to restore the moved block, using the output Herschel and looping around to the required position.
Fortunately, all the mirror images of the reaction are available because of the all-way symmetry of the block.
Here is the partial construction:

x = 66, y = 59, rule = B3/S23

The only tricky part might be allowing a clear path for the input glider.
The speed of recovery looks fairly good, because the output Herschel is generated quickly from the initial pi reaction.
I would love to complete this stable reflector myself but I don't think I would get to it for quite a while.
Someone with Hersrch should be able to find the right conduit in short order (hopefully).
Oh, yeah... the output glider for this reflector has to come from the Hershel conduit, which should not be a problem.
It won't win any prizes, but it might beat the record, who knows?
