All the buzz has been about colliding gliders to cleanly make a Sir Robin. But is it possible for a finite amount of Sir Robins to cleanly make a single glider? After all, the knightship's so big it's hard to clean any reaction up.

Colliding 35 pairs of Sir Robins like this can create any 35-glider synthesis, and one of these syntheses sends salvos of gliders in just the right way to destroy all the ash and release an extra glider:Hdjensofjfnen wrote: ↑October 21st, 2019, 8:23 pmAll the buzz has been about colliding gliders to cleanly make a Sir Robin.

EDIT: It would take a little more, since reflection reactions would be needed to get some of the closer gliders.

I don't think so; since every cell in the block dies at some point in the reaction it can't really be used in any other situation.Hdjensofjfnen wrote: ↑November 5th, 2019, 3:13 amWould this be known as a component, because it adds a 13-cell induction coil onto a block?

Mirage and Flying wing were both tagged for unclear notability at one point, but the tags were later removed because it had been judged that the consensus was to keep them. As for cheshire cat, it seems to be one of the many patterns and general terms taken from the Life Lexicon. In fact, it appears that

The LWTDS entry is a fairly unusual case -- deleted at one point because it's a term that no longer gets much use (if it ever did), but then brought back on general principles because it was in the Life Lexicon.

Most of the strange old irrelevant-looking stuff like Cheshire cat is in the Life Lexicon because it was in LIFELINE. And it's in the LifeWiki because Nathaniel basically started the LifeWiki by importing the 2006 version of the Life Lexicon.

It seems reasonable to leave these scattered "historical interest only" terms in place, since they do get mentioned in old articles and books about Conway's Life. But maybe it would make sense to add some kind of "This term is no longer in common use" template at the top of those articles, to help explain why it's there.

If I remember right, "flying wing" sneaked in to the LifeWiki because it got nominated for a Pattern of the Year competition, and got a few votes. So it became a case where people might stumble over the name and want to look up what it is, even if it's not a particularly notable advance in spaceship technology.

Is there a universal 2-lane monophase slow-salvo toolkit?

What do you do with ill crystallographers? Take them to the *mono*-clinic!

How about a new database that storages the way B-heptomino displace in some Life-like isotropic non-totalistic cellular automata? This can provide insights into the behaviours of INT rules.

In my imagination the information is stored in this format:
where gen=generations for B to reappear, dx and dy=offsets in two directions, orient=new orientation of B, isorulemin and isorulemax=range of rules for the sequence. Orientations follow the conventions for Herschel conduits:
For example, B in Conway's Life evolves into some junk and a new B at gen=64:
Then it is encoded as
Some issues I think of:

- The database includes no information about what actually the B is. Whether B is a oscillator, a spaceship, a replicator or merely a methuselah is not relevant to the offset. (But the new orientation does suggest behaviours.)
- Why B-heptominos? For me, it seems more likely to be observed in soups for INT rules than R-pentominos, Herschels, buns or block&gliders. But this statement may be biased and I can't decide on other small methuselahs like bookends, pre-loaves and Pi's. There's even the isomeric B-heptaplet. Moreover, unnamed methuselahs in other rules exist. (A survey on the most common small methuselah across INT rules?)
- The junks around the new B may interact with B so quickly that the characteristics of B is interrupted.
- Multiple B's can occur simultaneously.
- The B-heptomino may never appear again in the evolutionary sequence, but one of its descendants reappears and shows its features.
- The database can be exhaustive, but it may turn out to be randomly collecting stuffs like the 5S database.
