Re: Very nearly exploding rules

Re: Faster 2c/3 Wires
Darn, I didn't say that clearly -- I missed a rare chance there to say "substitute very nicely for a tau input". A 47-tick repeat time is pretty darn good. I think theoretically it might be possible to reduce that to 41 ticks with the same basic mechanism, but I'm not sure there's any kind of marke...

Re: Faster 2c/3 Wires
Here is a way to inject a 2c/3 signal with a repeat time of 61... Very nice find! A Herschel-plus-one-tick seems to substitute very nicely for a pi input, as long as there's a glider to back it up. The Herschel+glider is better because it performs a double-push -- i.e. a Herschel+glider is equivale...

Re: RCT remaining tasks
Oh, I have found a simplification in the ECCA design ... the direction switching does not need to insert glider before the direction semisnark. It is sufficient to make glider stopper on the line to prevent first of the G0 gliders to reach the semisnark, as the first glider is the decrement glider,...

Re: Spacefiller Recipe Working Thread
Good point. I had wondered about that, but had just assumed that there was some subtle crossing stream somewhere that would prevent all eight sets of longboats from being moved in. But they do all adjust inward just fine, up to 293 full diagonals: You could make the script move every longboat in as...

Re: Banks-V when
Since Banks-3 is the state reduction over Banks-2, I bet that Banks-5 will have 1 state less than Banks-4: Serizawa's rule has 3 states, rotate4reflect symmetry, the von Neumann neighbourhood, and is capable of universal computation and construction: https://onlinelibrary.wiley.com/doi/abs/10.1002/...

Re: RCT remaining tasks
The Pattern seed would wait alone roughly 8 aeons more for the glider from the last cordership destruction on FNW. I like it more this way, the seed of destruction has to sent only the signal destroying the (far) arm block. Rather to sending a LWSS to activate the pattern. How does the ATBC seed ge...
