### Non-explosive B2a rules

This is a thread for non-explosive B2a rules. One I find interesting is B2-ek4i8/S04et.

The couple known elementary oscillators:

Code: Select all

x = 28, y = 25, rule = B2-ek4i8/S04et
9bo2bo$20bo5bo$9bo2bo$22bobo$22bobo5$20bo5bo2$o2bo5bo2bo9bobo$6bo15bob o$o2bo5bo2bo2$6bo14bobobo$21bobobo2$19bo7bo3$20bo5bo2$22bobo$22bobo!

The right family is infinite, the only still life is the dot.

There are two common spaceships, a 6c/6 and a 4c/4:

Code: Select all

x = 9, y = 10, rule = B2-ek4i8/S04et
obo$6bobo$6bobo$obo5$obo$2bo!  The latter is way less common. There's almost a c/2 spaceship that can be turned into a wick: Code: Select all x = 16, y = 3, rule = B2-ek4i8/S04et bo3bo2bo3bo2bo$2o5b2o5b2o$bo3bo2bo3bo2bo!  The domino evolves into 4 dots and 2 6c/6 spaceships: Code: Select all x = 1, y = 2, rule = B2-ek4i8/S04et o$o!

Two dots can reflect a 6c/6 like so:

Code: Select all

x = 24, y = 4, rule = B2-ek4i8/S04et
obo20bo$6bobo$6bobo$obo20bo!  They create p30+12n oscillators. There is a replicator, shown here with an endpost: Code: Select all x = 28, y = 16, rule = B2-ek4i8/S04et o$o$o$o$18bo$12bo5bo5bo$12bo5bo5bo3$15bo5bo5bo$15bo5bo5bo$21bo$3bo$3bo
$3bo$3bo!

Moving objects:

Code: Select all

x = 82, y = 49, rule = B2-ek4i8/S04et
6bo$o5bobo$o5bo$6bo4$6bo$4bo2bo$obobo$o2bo2$2b2obo2$o2bo$obobo$4bo2bo$

Here's a p6 siderake for the 4c/4 and a variant of the 6c/6: Code: Select all x = 15, y = 9, rule = B2-ek4i8/S04et 2o2b2o6b2o2$3b3o4$11b4o2$12bo!
This is the first B2a rule I've ever seen with a natural p3, let alone such a small and common one in such a non-explosive rule.

EDIT: Unfortunately, it doesn't seem to be apgsearchable. I don't like how apgsearch handles B2a rules in general — square soups tend to generate too many multi-engine puffers and rakes on the edges. I may try my hand at a bit of hacking to create a pseudo-symmetry with some sort of alternative soup shape that's more B2a-friendly, but I don't have time at the moment (maybe tomorrow).

### Re: Non-explosive B2a rules

Your rule doesn't quite cut it because there is a natural breeder.

Code: Select all

x = 18, y = 13, rule = B2-ek4i8/S04et
2bo5bo$11bo5bo$11bo5bo$bo7bo$2b3o2$6b2o3bo$11bo5bo$11bo5bo$7bo3bo$2o4b o2$2o!

EDIT: You might be close to one that does work, though.

Code: Select all

x = 4, y = 3, rule = B3-q4z5y/S234k5j
2b2o$b2o$2o!

### Re: Non-explosive B2a rules

b2ac3qs0
b2ac3qs01c
b2ac3qs03ac (most apgsearched)

b2aci3q4qz5i6ns01c4a5k
b2ae3acr4eis2e3c4cw5k

similar family, has a 2c/18 rake

EDIT: and no replicators, unlike most B2a rules

Just place an alive ring of cells around it e.g.:

### Re: Non-explosive B2a rules

I know it's a natural breeder, but this is interesting oblique behaviour in a non-chaotically-explosive rule:

### Re: Non-explosive B2a rules

What is the pseudosymmetry called?

I'd like to try this rule in it.

Code: Select all

x = 76, y = 22, rule = B2ac3akn4ikt5qr/S03i
2b2o12bobo$15b2ob2o$b4o$37bobo$o2b3o30b2ob2o$bo13bo3bo15bo5bo32b2o$2b
2o33bobo34b2o14$18bo$18bo!

Interestingly, the second c/2 does not use the B2a transition. At the moment, it is the only known ship with this property.

Code: Select all

x = 4, y = 3, rule = B3-q4z5y/S234k5j
2b2o$b2o$2o!

I'm pretty sure someone else found a B2a-less spaceship before that.

I found some B3i and B1e agnostic ships, but the only ship I've seen on the forums that is B2a agnostic is that one. They posted that ship somewhere else a while ago, maybe you are remembering that. I may search for some more.
Wildmyron and I manage the 5S project, which collects all known spaceship speeds in Isotropic Non-totalistic rules.

Things to work on:

I went through the same mental process. Here's the original post.

One of the B2a rules with a pseudosymmetry census is B2an3ekr4i7c/S1c2ci3iqy4-a5678. The pseudo-symmetry is called ee9-test. I don't know if the modified hashsoup has been published, but the soups appear to all look like this:

Confirmed. However, I don't understand the existence of some linear growth pattern. Anyway - this is quite fast - almost 1000 soups a second. Unfortunately we don't get ships from this, just oscillators (and indirectly guns).

By the way - I think one of the most interesting B2a rules I know of.

In general - I think it is worth adding an 'eating' frame around the soup - B2an3ekr4i7c/S1c2ci3iqy4-a5678 is an excellent example - otherwise it would have been tough to find guns fr the periods p=7 to p=32.

### Re: Non-explosive B2a rules

This rule contains a ship that travels at 10c/14o. It was discovered by wildmyron (possibly using LLS) in January 2018. I rediscovered the same ship independently later on, but I can't remember when. Might this rule be apgsearchable with the border?

I would say that adding a border could definitely help with apgsearch-ability of this rule, but I don't think you could rule out that breeder appearing even with the border.
