Can someone add this P75 pi hassler to LifeWiki? I would add it myself but that would be adding my own discovery.

p75 pi hassler: there's some debris that forms really late. Also CatForce's torus setup means the pd's interfere, so can't use that to search. Tried some placements of 30P25 too, but no luck.

Code: Select all

x = 23, y = 62, rule = B3/S23

Can someone create a LifeWiki page for the Carotenoid? I feel like it should have one, but it doesn't yet.

Can "At present these are the only two clean waveguides known. " be removed from the Superstring page?

Note: I edited the Superstring page on 1 March 2026 to change "At present these are the only two waveguides known." to "At present these are the only two clean waveguides known." after I found the above superstring. However, I also found some superstrings that are not clean, like this one:

Should all versions of the undimensional spaceship be merged into one page titled "Unidimensional spaceships"? I was thinking about including a general definition of a unidimensional spaceship being any ship with at least one 1D phase, then adding the known versions under a header named "History".

On an unrelated note, I think the new four-digit Demonoid needs its own article.

I've made one (a while ago): https://conwaylife.com/wiki/Unidimensional_spaceship

[NooneAtAll3]

I still insist that "1D spaceship" is a better name that long unpronounceable "unidimensional"

I still insist that "1D spaceship" is a better name that long unpronounceable "unidimensional"

How about "1×N spaceship", matching the naming convention set by 1×N quadratic growth? Although with PHPBB search parsing × as a word boundary character, maybe it's best to swap it out for a lowercase x in both terms.

It seems like the term "unidimensional" has the most historical precedent. LifeWiki had an entry using "unidimensional" as early as 2009-05-27, and a blog post from 2008-06-10 uses the term as well. I couldn't find a Life Lexicon entry for either, so I imagine the terminology wasn't standardized.

In my mind, "1D spaceship" brings an association to the unrelated concept of one-dimensional cellular automata and seems to make less sense semantically.

I'm reading "Still Life Theory" by Matthew Cook (https://academic.oup.com/book/40819/cha ... m=fulltext)
the article is kinda about still lives, what makes them pseudo- and what doesn't.

Almost at the very start Cook displays this pattern:

Code: Select all

x=12, y=12, rule = B3/S23,
5b2o$5bobo$3b2o3bo$2bo6bo$2bo7bo$2o3b2o4bo$o4b2o3b2o$bo7bo$2bo6bo$3bo3b2o$4bobo$5b2o$

The "enclosed block" was designed (9/13/98) by Noam Elkies as the smallest example of one island enclosing another

I wonder if this part of GoL history can be added to the wiki somewhere, for historical purposes

This might seem insignificant, especially considering general... disregard for still lives in this community - but it comes from turbulent "middle ages" of GoL, when definition only began to solidify and approaches were shot down by counter-examples - like this one explaining why pure bounding boxes (bounded area overlap?) approach wouldn't work for separating still life parts

And the bonus of being "smallest" (by whatever metric) can be interesting too

---

Suggestion: replace beehive-with-tail example at https://conwaylife.com/wiki/Still_life with boat-tie (or maybe just add it without removing)

"has smaller still life inside" doesn't seem as problematic as "it still counts as 1 still life even tho it is made out of 2 - because they are connected"

Does this change the Velocities of Spaceships table found on the LifeWiki:Game of Life Status page
