They’re described in a file named “common-names.txt” which seems to have gotten most of its entries from Andrzej Okrasinski’s census. They seem to have been generated automatically but Catagolue didn’t inherit that code.
They are stored in all-common-names.txt. You are free to make a pull request, but no one has updated the file in nearly 3 years.

I prefer the second option (first generation with a fully formed spaceship) myself, it seems the most natural to me, and it's fairly easy to compute.I6_I6 wrote: July 18th, 2026, 10:16 am What's the standard "canonical" initial state of any gun?
So far, I've seen three: the first emitted spaceship right at the edge of the gun's bounding box (like in catagolue), the first generation containing a fully formed spaceship, or for synthesis-based guns, just before the synthesis begins.
In my opinion, the second option is the most useful for using the guns in larger patterns.

I don't think so, the 2nd HF is interrupted by a spark which is not part of the supporting oscillator, so it is not a true HF hassler.I6_I6 wrote: July 27th, 2026, 5:08 am Could it be considered a HF shuttle with offset (3,2)? If so, it might be the first with that offset (I can't find any with that offset in the collection in LifeWiki).

When you zoom out further than 1:1 the cells of the grid become smaller than the pixels of your screen, so each pixel corresponds to a square containing multiple cells. When smarter scaling is turned off then a pixel is coloured black if it contains any live cells, and white otherwise. When smarter scaling is turned on then the blackness of each pixel is equal to the proportion of live cells it contains. So 'on' gives you a more accurate impression of what the pattern looks like from far away, but 'off' lets you spot small patterns like gliders even when you are zoomed out a long way.
It basically means something was custom-made/designed for a very specific function.TheWayOfTheCon wrote: July 28th, 2026, 1:24 pm I've seen the word "bespoke" used as an adjective in a few LifeWiki articles, what does it mean?
Bespoke, in a general context, means created individually to serve a specific set of requirements - e.g a custom-tailored suit.TheWayOfTheCon wrote: July 28th, 2026, 1:24 pm I've seen the word "bespoke" used as an adjective in a few LifeWiki articles, what does it mean?
This means that the syntheses were manually created by a human rather than automatically generated by a program.slmake wrote:there are several 'bespoke' syntheses for unnatural objects such as Snarks and syringes
This means that rather than using a general-purpose p7 oscillator/sparker, a search was done to specifically find a period-7 oscillator that could complete the gun.Period-14 glider gun wrote:obtained by discovering a bespoke period-7 oscillator to liberate a glider from a p14 banana sparker by James Pascua.
This means that the algorithms were created for the specific purpose of soup searching.Life128 and vlife wrote:Life128 and vlife are bespoke algorithms designed by Adam P. Goucher and implemented in C++, used for soup-searching

Even if it's part of the rotor and gets rephased, the blinker is still part of the supports, so I don't think 54P23 should count as having stable supports. It wouldn't be a HF hassler anymore if you count the blinker as part of the active region.Rhombicubocta wrote: July 28th, 2026, 6:13 pm Does 54P23 count as having stable support since the blinker is rephased and can be interpreted as part of the rotor?Code: Select all

I think you can pull it out of the pslparse database somehow.I6_I6 wrote: July 29th, 2026, 5:26 am Where can I find basic single-channel recipes?
What's the cheapest single-channel recipe for building 2 blocks on the standard elbow lane and for pushing and pulling blocks? I need it for a weird sawtooth I'm building.

Replying to the question you made here, engineered diehards almost always contain Simkin glider guns and sawtooths. They are built the way they are because that permits them to have a longer lifespan before dying out completely.Nathaniel wrote: March 18th, 2016, 8:52 pm
