How to change the font size?

[Resu]

Does anybody actually use LifeWiki:Task list? The last edit was in 2023.

Seems in Pedestrian Life, Herschel is always from B-heptomino, but B-heptomino is always from R-pentomino. Should we also write R-pentomino on it?

The B-heptomino, just as in life, doesn't have to come from an R-pentomino in Pedestrian Life. The R-pentomino just so happens to produce a B, but it is not the only way (same with the Herschel emerging from B-heptomino)

I have posted something on the talk page of P32 blinker hassler 2. Quoting it:

Uhh... Should this be moved to somewhere like P32 traffic light hassler as that is more accurate? Or kept for historical reasons? After all, P26 glider shuttle and P31 glider shuttle were moved to P26 dependent reflector loop and P31 dependent reflector loop.

So, should the page be moved?

The first higher period c/4 orthogonal spaceship was discovered by David Bell in September 2000. It had a period of 20 and consisted of a block puffer found by Jason Summers and a side sparker used to delete the blocks. In the following month Summers found period 8 and 12 spaceships based off of a failed blinker puffer and a spaceship with a forward domino spark. Several other periods were achieved by perturbing the output of a period 168 puffer discovered by Paul Tooke in November 2003.

What spaceship is that?
c/4 orthogonal

[dbell]

What spaceship is that?
c/4 orthogonal

The description in the 'c/4 orthogonal' LifeWiki article is not quite right.

I remember finding the c/4 period 20 block puffer by adding a block and perturbing spaceships to the back of a period 4 spaceship found by Jason Summers.

Jason Summers then found a sparking spaceship which can delete the blocks to make a period 20 spaceship.

Here is the description and spaceship from the 'ships-c4o-hp.lif' file in jslife.

My own Life collection contains the following version of the block puffer, which I think is the original one I found, with the one in jslife using smaller perturbing spaceships.

Does anyone have a screenshot/some screenshots of the spam attacks in 2016? I am interested in this topic at the moment.
(idk if this is the right thread for this)

Hello, I found an account that is spam and should be deleted - 'gbwhatapps'
They have these fake government job links to make it seem like they are legit, but when I hovered over the 'website' I found it was a download link. Could be malicious, should be removed. Also, they were only online for 1 minute before leaving, and that is the only time they have been online.

Does the wiki use UTC, GMT, TAI, or something else?

It uses UTC.

Does the "Rule namespace" accept rules whose names begin with a lowercase letter?

[WRAPboi]

Can there be a LifeWiki page on puffers/rakes that move at the speed of light? (not GoL)

[Resu]

Is there anything that should be deleted in Special:UnusedCategories?

[I6_I6]

Pointing out that in Category:Patterns with 90-degree rotation symmetry (C4 symmetry), the p100 wing hassler is also included even though it doesn't have C4 symmetry:

Also, when creating a Wiki page, how do I put RLE in the infobox?

[I6_I6]

Should the p10 fountain have its own Wiki page? It's currently only in the Period-10 sparkers page.

[WhiteHawk]

Should the p10 fountain have its own Wiki page? It's currently only in the Period-10 sparkers page.

Probably not yet, since it hasn't been used anywhere, and most sparkers on that page don't have pages either even if they are used.

Also this is the thread for those sorts of questions.

[I6_I6]

Here's another update to the Sparker Stamp Collection. Thanks to JeremyDover, a lot of stators have been reduced, including this 118-cell variant of the P10 domino fountain:

Code: Select all

x = 26, y = 24, rule = B3/S23
9bo6bo$9b3o2b3o$10bob2obo2$12b2o2$5b6o4b6o$4bo6bo2bo6bo$2b3o6b4o6b3o$b

o18bob2o$2obo18bob2o$3bo18bo$3bobo14bobo$4b2o14b2o!

That should reduce a lot of patterns.
Should every pattern containing the p10 domino fountain in LifeWiki be fixed, or at least the article for it?
Also, it mentions Anivec's reduction, but the one in the infobox is by Mark Niemiec and it skips the reduction by James Pascua and doesn't reference the discovery of the long and narrow variant by wwei23.

[Resu]

There are lots of unused images in Special:UnusedFiles. Should the images be removed?

[I6_I6]

Should we merge all of the unidimensional ships into one wiki article? After all, they're technically all just reductions of each other.

Why not, but the last post is just a partial ... it is far from finishing V5.

I know, but I was just suggesting it.

[I6_I6]

Doublepost, but it's been 2 months already.
If I see that a pattern in say, one of the hassler pages, and find a simple reduction for it, should I replace the original pattern with the new reduced version or keep the original for historical purposes?

For example, this version of Bill Gosper's p24 TL hassler is 1 cell smaller:

Code: Select all

x = 19, y = 27, rule = B3/S23

3o$6b2obob2o$3b2o9b2o$3bo11bo$4bo9bo$3b2o9b2o!

...and a 4-cell reduction to a p38 LOM hassler by replacing the eater bridge eaters with eater bridge snakes:

Code: Select all

x = 94, y = 94, rule = B3/S23
