Glide symmetry and Flippers

Are there some examples of glide symmetric space ships that are not flippers? Because I have a feeling that that shouldn't be possible, and if so that should be mentioned explicitly. And Life Lexicon just says "A glide symmetric spaceship is sometimes called a flipper." Elithrion 06:25, 2 March 2009 (UTC)

Good call, you're quite right. I'll make the change now. Nathaniel 12:44, 2 March 2009 (UTC)

Splitting the article?

I'm not sure whether some of the sections on this page should get their own pages or not. While some seem like they might be significant enough, others do not. Also, greyships might be a good addition to this page (I described them slightly on the spaceship page). ~Sokwe

My thinking with this article was that it would be for brief definitions that wouldn't be large enough to warrant their own articles. If a particular section of this article gets long enough that it could stand on its own, then by all means it should be split (and I think that there might be enough information on Greyships to do just that, actually).

Non-monotonic spaceships

Concerning non-monotonic spaceships, the page says "The first example was found by Hartmut Holzwart in August 1992". That may be true for orthogonal spaceships, but not diagonal ones: Corderships, which were first built in 1991, are non-monotonic.

This also affects the "Bounding box" page.

Dean Hickerson,

Thanks Dean, you're of course quite right. I haven't been able to find any non-monotonic c/4 diagonal spaceship from pre-1991 in my collections so I don't know for 100% sure whether or not the Cordership was the first overall -- does anyone else know of an earlier diagonal non-monotonic spaceship?

I'm not sure if c/4 diagonal spaceships can be non-monotonic. At any rate, the only c/4 diagonal spaceships known before 1992 were the glider, the big glider, and big gliders pulling tagalongs.

"Flotilla 1" is referenced but not implemented. Spaceship flotilla which describes it is part of Glossary, not Patterns. Presumably making it a pattern would involve a Java script, which I am not prepared to contribute.

Knightships and other oblique spaceships

Technically, the term 'Knightship' refers to spaceships that travel at (2m,m)c/n (twice as fast vertically as horizontally); however, the term now seems to be used loosely to mean any obliquely traveling spaceship, and the article currently says that Gemini is the first knightship. Perhaps there should be a separate page to discuss oblique spaceships and puffers, with knightships as a sub-section.

Elementary and engineered

The page lists "classifications that apply to both elementary and engineered spaceships", but shouldn't there first be a paragraph or so that defines those terms? 77topaz (talk) 19:36, 7 March 2018 (UTC)

Probably. I've added a note saying "see below" for now; ideally these should have their own articles that we could link to there, with the paragraphs further down below giving a concise definition, and linking to said articles: ("Main article: ..."). Apple Bottom (talk) 20:31, 7 March 2018 (UTC)
EDIT: I've given knightships their own article; the other classifications listed on this here page are sufficiently short for this to not be a pressing concern. Apple Bottom (talk) 21:02, 7 March 2018 (UTC)
