Aw, dang. (2,1)c-horse was almost too good.
A few hours after the discovery of this ship, Goucher/Calcyman said he was still running the search based on Rokicki's partials, so there may be related patterns yet.HartmutHolzwart wrote:Congratulations! A real milestone in the history of CGOL!
I get it that there are no close cousins or small tagalongs?
Well, I heard about it before either of those but yes I'm new here specifically to join the congratulations.

No, I think we may have to wait another 14 years for that.calcyman wrote:Extrementhusiast, any hopes for a p210 gun based on this?Macbi wrote:I found the repeat time, which is 196.
Yeah, we'd need the glider synthesis first, right? And that would probably be very difficult to find.Extrementhusiast wrote:No, I think we may have to wait another 14 years for that.calcyman wrote:Extrementhusiast, any hopes for a p210 gun based on this?
Tom and I are intending to write a paper on the subject, and I'll post a (less technical) cp4space article describing the discovery and the ideas involved -- ideally could you please wait until then before 'going public'?Macbi wrote:I wonder if this will attract lots of new users to the forum in the same way that Gemini or Copperhead did?

Well, it's already been posted on Reddit, and anyone who sees this website can find out about it anyway, so it's basically already gone public.calcyman wrote:Tom and I are intending to write a paper on the subject, and I'll post a (less technical) cp4space article describing the discovery and the ideas involved -- ideally could you please wait until then before 'going public'?Macbi wrote:I wonder if this will attract lots of new users to the forum in the same way that Gemini or Copperhead did?

I mean prior to posting on Hacker News, Slashdot, and the like.77topaz wrote:Well, it's already been posted on Reddit, and anyone who sees this website can find out about it anyway, so it's basically already gone public.calcyman wrote:Tom and I are intending to write a paper on the subject, and I'll post a (less technical) cp4space article describing the discovery and the ideas involved -- ideally could you please wait until then before 'going public'?Macbi wrote:I wonder if this will attract lots of new users to the forum in the same way that Gemini or Copperhead did?

Well I already posted a link to HN but it didn't take off. I think a nontechnical article is needed for people to appreciate the brilliance.calcyman wrote:I mean prior to posting on Hacker News, Slashdot, and the like.
There's a couple more possible knightship speeds in that window, though, namely (2,1)c/7, (2,1)c/8, (3,1)c/9, (2,1)c/9, (3,1)c/10 and (2,1)c/10. We could easily exhaust the Knights of the Round Table before we exhaust our searching technology.Macbi wrote:I'd say the new most wanted speed is (3,1)c/8, since it's the simplest speed where it isn't know if it is achievable. Maybe the same tools can do the job? (With some slowdown due to the increase in period.) If they did manage to find a (3,1)c/8 then I'd expect a (4,1)c/10 or (3,2)c/10 to follow soon afterwards. After that the period might be a bit too high.
Although any new elementary spaceship speed is a good discovery, those aren't as interesting to me because we already know that ships can travel at those speeds (with much higher periods).77topaz wrote:There's a couple more possible knightship speeds in that window, though, namely (2,1)c/7, (2,1)c/8, (3,1)c/9, (2,1)c/9, (3,1)c/10 and (2,1)c/10.

This seems like a serious case of counting chickens before they're hatched, or spaceships before they're knighted.77topaz wrote:There's a couple more possible knightship speeds in that window, though, namely (2,1)c/7, (2,1)c/8, (3,1)c/9, (2,1)c/9, (3,1)c/10 and (2,1)c/10.

Nice! I'm sure there's something that recovers quicker, but nothing in my bag of tricks is immediately helpful, and the utility of faster recovery is... highly questionable.Extrementhusiast wrote:Eater Mk. I for Sir Robin (and not his minstrels), repeat time 557...
Three excess gliders, three pieces of debris to clear. Seems simple enough.
