Wow! that's a new smallest G-to-LWSS!

### Highway robber challenge

Can anyone find a way to reroute the southern Herschel output to replace the half-blockade? I recall that in the late 90s someone (Dean Hickerson? Dieter Leithner?) built a stable reflector which restored a half-blockade. x = 93, y = 84, rule = LifeHistory 45.A$46.A$44.3AB$45.4B$24.2A20.4B$23.A.A21....

### Re: How about a unidimensional spaceship?

To reduce complexity, I thought that a dynamic tape-reading head might be more appropriate. Here's one which should be relatively easily synthesisable: Adding another two basic rakes (on each side) is sufficient to produce a backward LWSS stream as output, which can then be fed into an interpreter:...

If making a quadratic replicator using the 0E0P metacell is overkill, maybe one could make a smaller one?

Right -- this tail is almost working, but the 6R forerake produces gliders on the wrong lane, which causes the displacement of the interchanges to be wrong, which in turn means that the resultant MWSSes end up on the wrong horizontal lanes and therefore spectacularly fail to clean up the six blocks:...

Good afternoon! In general, memorising patterns (other than very simple patterns such as the eater2 and LWSS) isn't generally done, because it's an unnecessary use of neurons (our brains are adept for creating new ideas; we have hard drives and SSDs for the banal task of memorisation).
