Elementary knightship

Postby calcyman » March 6th, 2018, 11:27 pm

This came out of ikpx (my search program, which is essentially a multithreaded hybrid of LLS and gfind) when I fed one of Tom Rokicki's long partials into it:

x = 31, y = 79, rule = B3/S23

Strictly speaking, 62% of this was discovered by Tom's earlier (abandoned) search, and the other 38% by my latest ikpx search.

It happened. It finally happened. Everyone give calcyman and Tom thunderous applause.

EDIT: To say something productive, it does have a strong back spark, but a distaff rake seems unlikely, since this ship is at its speed limit.

Okay, we have the POTY 2018. :o

I know it's only March, but I'm pretty sure...

Yeah, it's not possible for something to move faster at this slope. But, it might be possible if that spark had both glider-to-WSS and WSS-to-glider reactions, or a WSS-reflecting reaction (possibly using a stationary intermediate stage).

Woohoo! This one's been bothering me for a bit and I'm glad to see it finally unveil itself

I like that it doesn't have the same frontend as the 'almost-knightship.' I guess this would be a good time to ask, how is it that pretty much every speed in an active-enough rule (e.g. B3/S23) has a frontend? It would seem that it would be harder to find said frontends, but it doesn't take long for search programs produce a partial. I hope you understand what I'm asking, thanks.

I don't know when people started seriously searching for knightships, but this is the first elementary spaceship to have a new slope in 48 years. As well, it's been 14 years since the almost-knightship was discovered. Congrats!

Hmm.. what should this ship be named? My first idea would be something like "phantom", since the shape (well, of Rokicki's original partials slightly more than the full ship, but anyway) reminds me a bit of classic bedsheet-ghosts, and the ship was elusive for a long time.

EDIT: The ship and partials also somewhat resemble a seahorse, so that would also be a good option.

I assume you meant slope, since there are many other spaceships at speeds other than the glider and WSSes that are smaller than this one (e.g. loafer, dart).

It was terribly tempting to edit the original post and change one cell toward the end, so that the knightship didn't quite work.

Unfortunately April Fool's Day is still almost a month away... well. With great power comes great responsibility. With infinitesimal power comes a reasonably small amount of responsibility. I'll just add my congratulations, and say "welcome" to 282P6H2V1, until another name appears!

(Am trying to find some kind of pun, maybe on "C-horse" with the chess-knight connection. But "(2,1)c/6horse" just isn't very close.)

EDIT: I believe we're up to two dozen spaceship velocities now, counting the five infinite families only once each. Some of the infinite families -- Gemini, half-baked knightships, Demonoid, Caterloopillar, Orthogonoid -- may really be multiple infinite families, but it's too hard to count them if you start thinking like that.

Actually, some of the partials did look seahorse-like (and the full ship still slightly does), so "seahorse" could be a good name! :)

EDIT: For those who are curious, the ship's apgcode is xq6_yyocxukcy6gocs20h0a38bac2qq73uszyjo4w8y0e4mo0vu0o606s6444u08clav0h03g440qq1333333x11zy9ecec2ik032i210sw3f0hy011w70401011033547442zy0emj896he1e1kif6q2gc50ew9qb30dzgo403gg066m32w11z34407q441n6zy311. :o

Adam,

Now that you have your knightship, should we call you "Sir Adam"?

Then we should have Sir Tom as well! Your partials were a major step in the finding of this ship! :D

But then, what about Sir Andrew and Sir Dave who found the knight-Gemini?

Absolutely! Moreover, Tom modified iglucose to be compatible with FIFOs, which was necessary for ikpx to work at all.

First bit matches a partial I posted a while ago.

Just kidding. Congrats!

So who's going to find the first p7 kntghtship?

Well, we are crediting Rokicki for his partials, so... :P

Well, calcyman/we haven't decided on a name yet. Then again, it could first be added under the technical name 282P6H2V1, which I think was done for some other recently-discovered spaceships.

I don't think that's a good name, because what if another elementary knightship is found? Then that name would become ambiguous. I think a more descriptive name like "phantom" or "seahorse" or whatever would be better.

EDIT: I started a LifeWiki page for this spaceship under the placeholder name 282P6H2V1.
