### Re: Finding bottlenecks

HBx210E, HNE34T49, HNWT192, HNW2T196, and PF*198E share a common intermediate that is sometimes formed when a B-sequence is perturbed from behind. x = 9, y = 8, rule = B3/S23 6bo\$6b2o\$7b2o\$6b2o2\$2o\$b2o\$o! What phase of that post-B collision will be the canonical one? The first phase shared by all f...

### Re: Thread for basic questions

Shuttle is usually a subcategory of hassler (unless it's a RRO or RFO or R180°O etc.) My own mental reference for the word "shuttle" is actually not the analogy with vehicles (which could perfectly well go round in a circle rather than back and forth). A weaver's shuttle is the piece that holds the...

How can I make apgsearch(python or compiled) make the 'stdin' soups? (e.g. 4g) To clarify, as long as the symmetry is not recognized, the program will read RLEs from stdin instead of generating soups from SHA of a random seed, is that right? Does the symmetry have to end with 'stdin'? There's a new...

Why did you prefer RLE instead of apgcode?

I'm not as confident of my ability to get the picture exactly...

I don't think so. [chain of eater5s] That doesn't work too well. If we were concerned only about gliders coming from one direction (NW or SE), this would have a safety rating of 1/2. But gliders from the NE or SW destroy things 17/18ths of the time, which brings the total asymptotic rating down far...

I've never seen that occur naturally. Can you provide an example? Not that one in particular, but I've seen the related predecessor (where the bookend itself has an open hinge) occur occasionally.
