Is this the smallest single strict still life that produces an LWSS when hit by a glider?

Code: Select all

x = 13, y = 9, rule = B3/S23
bo10bo$b3o6b2o$4bo6b2o$3bo2bo$3bob2o$2b2o$3bo$3o$o!

No, Pentadecathlon.com lists this 14-cell still life:

Code: Select all

x = 10, y = 7, rule = B3/S23
b2o$o2bo$bo2bo$2b2obo$4bo2b2o$bobo3bobo$b2o4bo!

That has 15 cells. I've independently found another SL with 15 cells that fits the criteria:

Code: Select all

x = 11, y = 7, rule = B3/S23
bo6b2o$2bo4bo2bo$3o2bo2b2o$5b2obo$8bo$8bobo$9b2o!

That "14-cell" still life is 14 cells.

About 15 years ago I finished up a survey of all collisions of a single Glider with all stable objects of up to 17 bits in size, and oscillators up to 16. Here's a sample of the smallest objects producing all three size Spaceships--

Code: Select all

x=11, y=38
2b2o$o2bo$3o2$2b3o$bo2bo$b2o2$3bo$3b2o$2bobo8$6b2o$b2o2b2o$o2bo3bo$4o2$2b
2o$3bo$3o$o5$2o3b2o3bo$obobobob2o$b2obo4b2o$4b2o$4bo$5bo$4b2o!

And try this one for amusement, the longest lived--

Code: Select all

x=9, y=10

That "14-cell" still life is 14 cells.

So it does. I forgot to erase one of the glider's cells.

Hey everyone, I stumbled across a 5-cell pattern in a 3x3 bounding box that lasts 1104 generations, so 1 generation longer than the r-pentomino.
I would be surprised if no one found it yet, since it is so small, but I'm still putting this here since I could not find it anywhere:
x0x
xx0
x00
Does anyone know if this pattern has been documented yet and if yes, why it is not in the wiki "list of long-lived methuselahs"?

Thanks!

I'd recommend evolving it one generation and then looking at it

[computer_kid]

Ah, that explains why it lasts exactly one generation longer than the r-pentomino
Thanks!

The pi+boat reaction on the left around gen 69 is a good way to synthesis adjacent bookends. It is even compatible with 3G boat-tie-house reactions, which has fifteen 3G pathways (duplicates not excluded) according to synthesise_patt_v1.2.py:

With some edgeshooting house and boat-tie-house reactions, a wickstretching mechanism is likely doable. However I've not found one.
It's also notable that in the quote above there is one of the eighteen 3G reactions giving a boat+pi combo at sweet spot.

Is everything above known?

It's not known to me (not that that means all that much, glider synthesis not being my strong point).

I'd say that if Catagolue doesn't know that 7G recipe for the 28-bit still life, the mechanism can't be too generally known.

The mechanism of attacking a boat (or otherwise anchored tub-like bonding site) with something with an attached line-or-two, like a ship, has been known for a long time. However, I don't recall it ever being used to add a house to make a line-of-five.

However, the reverse has been known for a long time. Dave Buckingham used it in his Hustler synthesis; it's one of the steps in the mechanism to move an inductor from one side of a billiard table to the opposite side (which is probably doable with 3 gliders today).

With the recipe that starts with a boat and ends with a new tied boat, this wickstretcher recipe comes to mind immediately:

Is this known? I don't see it anywhere else (p16 bumper):

The bumper is known and the Rob's p16's interactions are known. This could be considered new, but anywhere it could be used, a p8 bumper could be used, and the oscillators used for p8 bumpers take up smaller space than Rob's p16.

[Entity Valkyrie 2]

I updated the bumper and bouncer gallery.

EDIT: That was risky, since it was too late I found that it wasn't in my list of "galleries" in my user page. However, it seems like I've made almost all the edits in this page (other than one edit by Ian07).

EDIT: Both of the P16 bumper variants have a smaller bounding box than the p8 bumper with the blocker.

You've discovered (or rather, posted) it first but it had already been imagined/thought of before.

It has a few weak sparks, so it will probably give some smaller LCM oscillators, although I'm not sure if it will be useful beyond that.

Unfortunately, I wasn't able to reduce any other low periods using this, as the spark is too close to avoid destroying the oscillator. p240 can be easily done using a pentadecathlon, but it looks like the p48, p80, p96, and p144 pages won't need updating unless I'm missing something. Either way, massive congrats to Rob Liston!
