Hello, it's my first time on this forum.

I have discovered this pattern, a 41 block long line that generate 12 blocks, 4 beehives, 4 loafs and 4 pulsars.

I don't know if it's interesting, but i didn't found someone talking about it. I think it's a beautiful way to make 4 pulsars.

Code: Select all

x = 29, y = 44, rule = B3/S23

The 1-by-n rectangles of alive cells were an early "thing to investigate".
The 41-by-1 rectangle is mentioned in One-cell-thick_pattern#With_all_cells_alive.

It's new. There was a list of all known oscillators on the forum that was updated today, and this isn't in that list.

[Vlev2]

I discovered a 2 patterns but I am not sure if I create them.
#1: Sun
The Sun is a spark with a 5x5 bounding box and, with a lifespan of 2 generations and evolves into 4 dots.
This is what it looks like:

OOOOOOO
OXOXOXO
OOXXXOO
OXXOXXO
OOXXXOO
OXOXOXO

#2: Stable Wheel
I just discovered it today while searching for another pinwheel oscillator and I couldn’t figure out a name, so I named it a stable wheel. It is a strict still life with a 12x12 bounding box that looks like this:

OOOOOOXXOOOO
OOOOOOXXOOOO
OOOOOOOOOOO
OOOOXXXXOOOO
XXOXOOOOXOOO
XXOXOXXOXOOO
OOOXOXXOXOXX
OOOXOOOOXOXX
OOOOXXXXOOOO
OOOOOOOOOOO
OOOOXXOOOOO
OOOOXXOOOOO

This is all I have here. Thanks for reading!

Welcome to the forums!

The forum software "eats" the leading whitespace in each line, which can be prevented as follows:

Here is my attempt to redraw the patterns in Golly and copy-and-paste them into the forum post as RLE snippets:

Code: Select all

x = 24, y = 12, rule = B3/S23

10bo4bob2o$b3o12b4o$obobo$16b2o$16b2o!

(edit: fixed second pattern)

The still life can be seen on the page xs36_gg0g88bbgz11078bb87066zy033, and has a known glider synthesis (this is also true for many other still lives, though).

Usually, neither hand-drawn big sparks nor big still lives are considered "interesting" or "noteworthy", unless a specific spark or a specific still life has some nontrivial/rare application (such as being useful for creating a rare reaction or performing a rare catalysis).

A kind of AND Gate with Herschel between LWSS.
The LWSS passes through the conduit if the H is not there.
A NE Glider is emitted if H and LWSS are there.
If the LWSS is not there, the conduit works as it had to do.

The LWSSes are on the same lane for the 2 patterns.
So there is 2 timings in 1 lane :
- one extracts a NE Glider
- one extracts the F116's NE Glider

Each pattern has a RT138 due to the F116 conduit.

[Vort]

hey! i may have found an interesting pattern. i was inspired by the two-glider mess and wanted to go for something that would beat it somehow.
after a bit of tinkering with three gliders i came across this pattern which lasted me over 2400 iterations, and made quite a mess indeed.

Can you post the pattern?

If you are using Golly or LifeViewer, you can copy the RLE out of the program, and paste it as a plain-text snippet between tags [pattern] [/pattern]
For example, here I pasted the glider:

With initial bounding box 7-by-3 and initial population 10 bits, it's unlikely to be "new" (small patterns were repeatedly enumerated for different purposes).
It's also not too noteworthy as a methuselah, because its lifespan is only 572 ticks. The simple R-pentomino (or the F-pentomino, if you prefer Golomb's notation) is a methuselah with initial bounding box 3-by-3, initial population 5 bits, and lifespan 1103 ticks:

Code: Select all

Check this page: List of long-lived methuselahs

In most cases, what appears to be a "new methuselah" is either already known, or nonnotable (because there are examples that last longer for the same or smaller initial bounding box area, and for the same or smaller initial population), or both.

Probably not of much use.

Of course, I am probably only beating a dead horse here by posting this. I hope it doesn't bother you too much

[confocaloid]

I think I already used this pattern in a wick:
[...]
Of course, I am probably only beating a dead horse here by posting this. I hope it doesn't bother you too much.

Not exactly "this pattern", though. As far as I can tell, the exact pattern never occurs during evolution of the fuse. It looks more like another predecessor of a later generation of that pattern (converging sequences).

Additionally, I'm not sure whether "used this [sequence?]" is a good way to describe the situation when the evolutionary sequence "just so happened to" appear in a pattern, without an intent to use that particular sequence.
(For example, even though the Herschel happens to appear in the evolution of the R-pentomino, it would be a bad explanation of the situation to claim that "the R-pentomino uses the Herschel".)

I think I found a 5-cell that takes 2 generations longer to stabilize. I'm new to the game, so IF i'm counting correctly it dies after 1,105 instead of 1,103 like R-pentomino. IF it's really a new discovery, and IF I get to name it, I'd like Juno for the J shape.

Sorry if I broke all the rules. I couldn't figure out the RLE thing.

Lifeline Volume 4 enumerates all patterns with 6 or fewer cells. (The 7 column only counts heptominoes, not all 7-cell patterns.)

Its lifespan is 2 ticks higher than the lifespan of R-pentomino, because it evolves into the R-pentomino two ticks later.

If you know about the R-pentomino, and if you are interested in notable long-lived patterns, then the pages List of long-lived methuselahs and LW:NB should be helpful.

Strangely enough, 2 glider match another 3-glider recipe, and gives another long boat with same parity and orientation, (but different lan for reflections, allowing a shift by 12. Also, it is built outside of the reach of the lane of gliders used in the synthesis.
