Re: Thread for your chaos-edgeshooting reactions that can probably yield new conduits

Speaking of only having two ∏→∏ conduits, how do we not have a PF30 conduit (extracting the ∏ that already forms in the ∏-heptomino's evolution 30 generations later and 9 cells ahead)? Well, there is this thing: #C pi-heptomino conduits: Dean Hickerson, 17 February 1997 #C Herschel-to-pi stage by P...

Re: Agar discussion thread

Has anyone thought about how to define apgcodes for agars and wicks? I'm approaching 80,000,000,000 soups in T29x33 and I've got quite a few duplicates. I can assign apgcodes to the bounded patterns that crop up, but I'd like to do something similar with the unbounded ones. They don't have bounding ...

Yes - they do interact on their own, don't they? It just takes a couple of cycles for them to get there. Doh.

Yup, it's easy to construct agars with arbitrarily large periods. What about naturally occurring ones, though?

I figured that I therefore might be able to get some useful advice for you, like how to sort through all of the ideas and figure out which are the most practical.

I had a hunch that there might be interesting things lurking in the non-square toroids, which I haven't heard of anyone trying to search before. I wrote a basic searcher that runs on an FPGA. It chooses random soups, runs them until periodic, throws out all the p1s and p2s, and reports the rest to s...

Wouldn't that only rule out gutter symmetry? There is a live stator cell in the gutter immediately below the two central rotor cells. It remains live throughout, despite the cell above it both living and dying. This can only happen if it has exactly 2 live stator neighbours. In a symmetrical config...

Can it be made symmetric?
No. Two cells in the central column become live. They can only do this if they have 3 live neighbours, which is impossible if the pattern is perfectly symmetric.
