And a pre-pulsar wick, which can probably be stabilized similar to eureka:

This Wave is (3,3)c/30? If yes could it be stabilized by c/10 rakes to build a diagonal wave stretcher?

Not sure if a diagonal c/10 rake exists, but one could use a p18 c/3 orthogonal rakes instead.

I tried to find a way to support the ends with gliders. Best I could find is this, but the gliders are too close to make the reaction repeatable:

Code: Select all

x = 22, y = 23, rule = B3/S23

I did find a 6c/60 reaction for a pre-pulsar though based on it, so we can probably push it along using c/10 rakes:

Code: Select all

x = 99, y = 168, rule = B3/S23

I actually meant c/5 orthogonal rakes. Something similar to the diagonal heptomino wave. Not sure such a rake already is available.

Edit: jslifemoving only has a p 60 c5o rake. Maybe some trick using kickback might work to produce the p30 glider stream?

Posted: **October 12th, 2025, 3:23 pm**

Turns out... one only needs 2 glider steams to support this thing... 0_o

Was experimenting with shillelaghs until I decided to merge two together then I got this

Code: Select all

x = 6, y = 6, rule = B3/S23
2o$o2b2o$b2obo$3bo$3bobo$4b2o!

Its a still life but i couldnt find it on LifeWiki

It can be infinitely extended too

Code: Select all

x = 9, y = 9, rule = B3/S23

I find it interesting that combining two shillelaghs is still just a still life
I think someone else has definitely tried this too and got the same result so I dont think its new

Welcome to the forums! The still life is not new and is indeed documented on the wiki, but not on its own page - it's #48 on List of still lifes with 13 cells. It doesn't appear to have a name yet, but a variant with a tub instead of a boat at the edge is called claw at claw. Most modern focus on still lifes has been about still lifes with special useful reactions, or synthesizing all of them up to a given population.

Catagolue's object page can be a good tool to find out the names of specific stable patterns, but not all have names.

Thats why I couldnt find it on lifewiki! It was unnamed!
Thanks for letting me know!
If I can call it a name, I would call the still life "shillelagh siamese shillelagh"

Now I'm wondering: how far can this pattern possibly be reduced further?

Lastly, this reduction might be notable enough for an edit on LifeWiki, maybe it will be the first time i get mentioned on the wiki!

Welcome to the forums! Unfortunately, 'new' methuselae that stabilise quickly are not considered notable. There are simply too many, and they have few practical applications to other areas of the Game of Life. There are millions of methuselae fitting in a 16x16 bounding box that last longer than 25000 generations, so 310 generations is not significant.

Now I'm wondering: how far can this pattern possibly be reduced further?

Since the backrake 1 reduction is glider-constructible, the pattern can probably be built by an RCT, meaning that the initial population can in theory be reduced to 61 (based on LifeWiki DYK 152), but like all RCT-based arguments, such a pattern would be incredibly impractical.

Yesterday I was just experimenting in the game of life. I created a cannon and placed a spaceship on its trajectory, but after the collision, I accidentally created a steam locomotive. I wonder if this is a brand new locomotive or if there already is one. It leaves traces in the form of 2 x 2 cubes on a trajectory resembling a sine wave.

Btw, spaceships that leave exhaust behind as they travel are called puffers and stationary objects that continuously shoot spaceships are called guns.

Welcome to the forums!

This pattern has likely not been mentioned previously, and it doesn't have a name. However, active regions like this aren't usually particularly notable — this region isn't even in the top 50 active regions.

Also, it's better to use [pattern] tags instead of [LV].

I am working on a p6210 58P5H1V1 gun that uses this reaction, only with a period 690 stream filtered to period 2070, which then gets filtered further to period 6210 by a p2070 gun with a 56P27 deleting every third glider.

My 19-cell pattern changes after 13 steps to this 14-cell pattern:

Code: Select all

that delivers a stable system in step 2445 (Golly) and with your LV in step 2432.
