Re: Spaceship Discussion Thread
Here's a partial c/7 that I found from searching ships with width 11 gutter symmetry: Logical width 11 seems wide as a starting place for c/7. I don't think anyone's ever tried to find a gutter-symmetric c/7 orthogonal ship at logical width 10 (full width 21). Any such search would find two loafers...

Re: 2x2
Sokwe, qfind appears to output spaceships in ascending order of length, does it conduct a breadth-first search and guarantee minimal length? It runs a breadth-first search, but also uses depth-first look ahead to prune. If it finds a ship during the depth-first look ahead it will print it, and this...

I tried a b2f search for a 3c/7 back rake, as crazy a long shot as that is. I still think the following idea might be the best shot at a p7 backrake: Here's an idea for finding a period-7 3c/7 rake that might be feasible: The glider releasing reaction in the p21 rake is more reliant on the spark fr...

I got something like the second solved but it's not clear if it will actually be useful as the branches on that back (east) side are pretty big and possibly in the way. Wow, that's some crazy branching! However, I think it will be useful. The following high-period chaotic puffer seems to have a bas...

Re: amling questionable searches/ideas firehose
Alternate back edges to the recent c/4 diagonal puffer engine with slightly different sparks could give variant puffer engines that behave differently. Here are two related partial results, the first probably being easier to solve, but the second giving a more resilient engine: x = 168, y = 29, rule...

I guess it just seems rather hemmed in, stuck searching upward, and subjectively the rate at which search results were lengthening with widening windows seemed poor.

That sparker with that clearance is quite demanding.
