### B38/S23

This topic is (obviously) for posting discoveries in the rule B38/S23. I will start things off with a left-turn Herschel conduit (I don't know how the numbering scheme works, or I would number it):

Code: Select all

``````x = 54, y = 38, rule = b38s23History

Very nice. It would be referred to as a L151 (a left-turn taking 151 generations).

Much of the stuff from B3/S23 also works in this rule. Additionally, there's a natural puffer and natural gun.

Code: Select all

``````#C 31c/589 diagonal puffer:

``````#C p424 statorless glider gun:

### Re: B38/S23

To reiterate a discovery mentioned on the Soup search results in rules other than Conway's life thread, a new (5,2)c/190 oblique spaceship has appeared from a C1 soup for this rule. It has a minimum population of 33 cells:

Code: Select all

``````x = 28, y = 40, rule = B38/S23
26b2o\$26b2o5\$21b3o\$21bo\$21b2obo\$23b2o9\$13bobo\$13bo2bo\$13bobo2\$12bo\$5bo
7bo\$3bobo6bo\$3b3o12\$b2o\$obo\$bo!
``````

It can be synthesized by creating two Rs that interact with a boat (8 gliders total):

Code: Select all

``````x = 52, y = 71, rule = B38/S23
o\$b2o\$2o36\$12bo\$10bobo\$11b2o10\$50bo\$49b2o\$2o47bobo\$b2o\$o\$26b3o\$11b2o
13bo\$10bobo14bo\$12bo6\$17bo\$16bo\$16b3o2\$16bo\$16b2o\$15bobo!
``````
Two of these spaceships can interact to produce a glider rake:

Code: Select all

``````x = 55, y = 50, rule = B38/S23

### Re: B38/S23

Seeing this ship fills me with determination. I mean, couldn't a technology so small exist in Life? Although one hasn't turned up yet...

Also, does anyone have a synthesis for the traffic light? Making them is indeed possible, but the normal Life blinker synthesis does not work:

### Re: B38/S23

There's apparently a reasonably common dirty orthogonal puffer as well as the diagonal one. Together with the natural gun and the oblique spaceship, this means that B38/S23 has at least four completely independent high-period mechanisms:

As well as the Snark working correctly in B38/S23, so does Simkin's glider gun (suggesting possible interesting shenanigans involving p120 oscillators).

I think I might be tempted to prefer B38/S23 over GoL, actually...

### Re: B38/S23

A new variant of the P190 (5,2) oblique ship has appeared on Catagolue. This one functions in the same basic manner as the previous spaceship, but the colliding R's are phased slightly differently. The minimum population of this ship is 32 cells (as opposed to 33 for the other variant):

Code: Select all

``````x = 24, y = 42, rule = B38/S23
22b2o\$22b2o4\$18b2o\$20bo2\$19b2o\$20bo10\$14bo\$13bobo\$12bo3bo\$13bobo\$14bo\$
5bo\$4b2o\$3bo2bo\$3bobo\$4b2o11\$b2o\$obo\$bo!
``````
It arose from the following soup:

``````x = 16, y = 16, rule = B38/S23

By the way, I think this class of spaceships/puffers/rakes is interesting enough to deserve a proper name. May I offer the name "Flying Dutchman" as a suggestion, since it looks like a cloud of 'ghosts' flying a boat into the sky (when you point it in the right direction)? It might be more apropos if this were a 'ship' instead of a 'boat', but a boat is close enough.

EDIT: Another spaceship variant has appeared. This one has a minimum population of 37 cells, which occurs twice. Here is the smaller of those two configurations:

Code: Select all

``````x = 25, y = 39, rule = B38/S23

### Re: B38/S23

Seems like this family of spaceships is cropping up a lot. There seems to be many variants, each of which have only occurred once thus far.

Which has the smallest minimum population?

There are at least 692 variants that can be formed by the placement of the boat and two Rs in various positions and phase differences. The pattern file attached below shows all 692, with the vertical scale being the relative phase difference between the two Rs, and each functional spaceship with that phase difference listed horizontally. The boxes mark the ships that have been found thus far in Catagolue.
b38s23-oblique-ships.rle
692 oblique ships in b38/s23
Perhaps the most interesting of these is the one ship that has the two Rs in exactly the same phase (the fourth ship from the top). This means that the following simple pattern is an oblique ship predecessor in b38/s23:

Code: Select all

``````x = 12, y = 37, rule = B38/S23
2bo\$3o\$bo18\$11bo\$9b3o\$10bo12\$7b2o\$6bobo\$7bo!
``````
With this many ships, and assuming each one has a roughly equal probability of occurring, the expected number of ships that would have to appear out of soup before we get the first duplicate is 32. (This is a variation of the well-known matching birthdays problem, with the 'year' being length 692).

In addition to these 692 spaceships, I was able to find another 120 infinite growth patterns, which includes glider rakes (in all 4 directions), puffers, puffer-rakes, and even one double-rake. Boxes mark the ones found in soup so far, with a double box around the rake found by AbhpzTa:
b38s23-oblique-puffers-and-rakes.rle
120 oblique puffers and rakes in b38/s23
All of these ships and puffers are formed from the same three components, and each should be constructible with a maximum of seven gliders; three for each R and one to trigger the boat production. This does not exhaust all of the possible ships and puffers, however, since the possibility exists of there being variants that require external stabilization (an additional component that keeps the interaction debris from destroying the puffer/ship, much like a block is needed to stabilize a switch-engine in Life). Searching for such stabilizations would be a much more time-consuming task.

Though I haven't measured them all, this would likely be the same-phase ship, because the two R clouds will reach their minimum population at the same time. This minimum phase has a total of 25 cells.
