I have made some major edits to this page as I found that the old page was somewhat difficult to read. I would like to see more added to the history section of this page, especially more references. My initial idea for that section was to provide information on the various searches that people had made, as well as the discovery of new spaceship speeds, but other information on the history of spaceships would also be nice. Also, if somebody would rewrite some of this page so that it used the word "spaceship" somewhat less, I believe that would be helpful.

I was wondering if separate pages should be made for each spaceship speed, in addition to the categories of patterns that travel at those speeds, as I find that the category pages don't provide the necessary information that one might be looking for when going to such a page. I also believe that pages should be made for individuals who have made significant contributions to life.

More in relation to this page, I was wondering if the table of smallest known spaceships for a given speed should get its own section in this article, or whether it should be put in a new sub-section with other information. I am assuming that the table of spaceship speed discoveries will be in the history section.

Update: I added more to the history section, I am also going to create a "Spaceship types" section (with a link to Types of spaceships) to describe things like greyships and tagalongs, as well as to put the table of smallest spaceships in.
Update 2: I added names for several unnamed spaceships missing from the tables on this page. These additions are, to the best of my knowledge, correct. The names refer to the following patterns:
I also added a new section (Spaceship types).

Update 3: Pages for all of these unnamed spaceships have been created, thanks to Nathaniel.

Personally, I would rather see the category pages themselves expanded to include any relevant information about the spaceships of that speed (the first one found, the smallest one known to date, etc) rather than creating a separate page for that information and then having the category as well. Similarly with the user contribution pages, though that might be more questionable if we have a lot of information for a particular Life guru (such as Conway, Hickerson and Bell). I protected some categories early on but I don't know why I did that, so I'll remove the protection from the speed category pages, and feel free to ask me to remove protection from any other page you'd like to expand/alter. Category pages can have text added in the exact same way as normal text pages.
Also, just so you know you can sign your post automatically by typing four tildes: ~~~~ will be replaced automatically by your name and timestamp. Also, I'll add some pattern pages for the spaceships that you added to this page. My thinking is that if a pattern holds a record that is notable enough that it's mentioned on another page, then that pattern probably deserves its own page. Nathaniel 03:56, 19 April 2009 (UTC)

I noticed that the tables with spaceship speeds are organized by the size of their denominator. I was wondering if perhaps they should be ordered by relative speed (still keeping the directions separate), thus making the order: Diagonal: c/4, c/5, c/6, c/12; Orthogonal: c/2, 2c/5, 17c/45, c/3, 2c/7, c/4, c/5, c/6 (The first discoveries table could possibly be ordered by date of discovery). I've noticed that the convention in the life community seems to be the way in which the tables are currently ordered.

The mathematician in me agrees that in general things like this should be sorted by their actual value, but I personally think it's easier to read the way it is, since it's not completely trivial to determine whether or not 2/7 is faster or slower than 1/3 in your head. I don't care a whole lot either way though.
Also, I've found most of the other spaceships, but can I ask where you found 295P5H1V1? I'd like to add a page for it and it would be a lot easier to do so if I could track down an RLE file (or similar file) for it. Nathaniel 23:09, 22 April 2009 (UTC)
Nevermind, I found it in Jason Summers' pattern collections. Nathaniel 23:25, 22 April 2009 (UTC)


It would be nice if someone could sort the orthogonal spaceships by their speed (c/2, 2c/5, 17c/45, c/3).

Also, why the hell are shield bug and centipede not with the rest of the orthogonal spaceships?AwesoMan3000 (talk) 11:28, 18 February 2016 (UTC)

I've done this for the second table. Feel free to revert if needed. - AwesoMan3000 (talk) 08:41, 19 February 2016 (UTC)

Should weekender distaff be included in the engineered spaceships section?

Weekender distaff is just an engineless rake. We have such rakes for many other speeds (c/3, c/4, c/5, 2c/5 orthogonal and c/4, c/5 diagonal). It seems we should either include all of these or none of them in the table.

You're right, it's a stretch to fit the weekender distaff into this table. The "specific active reaction that travels at one particular speed" would have to be the weekenders, which can travel unsupported. So an engineless rake (or high-period traveling loop, whatever you call that, if it's like an engineless rake but doesn't emit any gliders) shouldn't be in quite the same category as a supported active reaction.
That said, it seems like a reasonably good idea to add an "engineless rakes" section at the bottom of the engineered-spaceships table, with all seven known types. They do share some commonality with engineered spaceships. Dvgrn (talk) 10:40, 25 October 2018 (UTC)
