wildmyron,

I think that in order to get Precursor X-Rule you obtain a variant of Precursor X-Rule that show the wonderful behavior that we see in the previous post.

Precursor X-Rule rule is:

Well I guess it was too much to hope that my manual translation of the ruletable was error free. The conversion of the p8 ship into a p16 puffer should have been a warning bell. The errors are in two transitions: S2i and S3c - which leads to the correct notation for the x-rule precursor of B2eic3ic4rnj5ink/S12aein4qiyne5re6aei8. Here is the correct rule table for anyone who wants to experiment with the rule:

Before I post a complete rule file, does anyone have a suggestion on how to sort out the naming mess?

Posted: **November 5th, 2015, 10:16 am**

I'd just call this one pre-x-rule... It's a lot less clunky than
B2eic3ic4rnj5ink/S12aein4qiyne5re6aei8, at the least.

Code: Select all

@RULE pre-x-rule
This rule is B2eic3ic4rnj5ink/S12aein4qiyne5re6aei8.
It is an isotropic 'precursor' rule to a non-isotropic rule known as x-rule which has been shown to support logic universality by J.M. Gomez-Soto and A. Wuensche.

[1] Gomez-Soto,JM., and A.Wuensche,“The X-rule: universal computation in a
non-isotropic Life-like Cellular Automaton”

This is a two state, isotropic, non-totalistic rule on the Moore neighbourhood.
The notation used to define the rule was originally proposed by Alan Hensel.
See http://www.ibiblio.org/lifepatterns/neighbors2.html for details.

Nice rules! The original x-rule precursor looks far more stable.

Code: Select all

x = 21, y = 1, rule = pre-x-rule

Any hope for this into something like a gun? Probably not but just in case...

Not sure about this but I'm fairly sure you'll be able to conjure something up with one of the oscillators above.

Edit: Corrected misplacement of p6 oscillator in p4 row.

Yes, I really should post a work in progress - I've been hesitating because there are quite a few issues resulting from the way that apgsearch is tailored for B3/S23 and because of uncertainty over which version of Hensel's isotropic rule notation to use. However, quite a few rules have recently been referred to using the neighbors2 version (including by me) and that was the one which I implemented.

Got it! My approach was a bit indirect though.

First, danieldb's forward rake was modified to produce this p24 Gb backrake:

Code: Select all

x = 26, y = 27, rule = pre-x-rule
2$2b2o$bo$2b2o$17b2o$16bo$8bo8b2o$8bo5bo$2bo3bo7bo$3o2b2o10b2o$3b2o11b

Then, the bi-domino glider reflector allowed for a period-quadrupling reaction that creates tethered rakes:

Code: Select all

x = 61, y = 41, rule = pre-x-rule
36bo$35b3o$35b3o2$34b5o$36bo7b2o$34b5o4bo$44b2o$35b3o21b2o$35b3o20bo$

3o$36bo2$22bo$22bo$22bo$22bo$21b3o$20bobobo$21b3o$22bo$22bo$22bo$22bo!

The resulting period of the glider streams is 192: 24*4*2(magnitude of the doppler effect at c/2).
Note that p12s are used to eat the stray gliders--I couldn't find stable eaters for some reason.

p192 is now large enough to allow the synthesis to take place:

@thunk: Nice work with the breeder! I'd seen that reaction with a similar backrake but it just didn't occur to me to use them like a gun.

@jmgomez: the spiral is quite mesmerizing - but it seems to only work in x-rule-pre, i.e. the rule which is not actually the precursor to the x-rule (could you edit the posted rle accordingly please?). I haven't yet found a conversion reaction from Ga to Gc in pre-x-rule - are you aware of one? On the ddlab website I saw mention of a spiral gun rule. is that a rule which supports a similar pattern or is it something different again?

Here is a p19 double barreled gun for glider Gc. Readily synthesisable by two different methods.

@wildmyron:

Yes spiral is amazing, and you right it is not work in Precursor X-Rule (the original), and I don´t know yet if this rule have a spiral, I will try it

Sorry for cause confusion

My code will be (in x-rule-pre):

Code: Select all

#CXRLE Pos=-30,-20 Gen=2271
x = 106, y = 41, rule = x-rule-pre

By the way the Spiral I post is more modest that the Spiral you see in Ddlab,
Ddlab one is a spiral-glider-gun.

This again only works in x-rule-pre (wildmyron's unintentional modification of the precursor).
The P15 (along with a P27) was featured in the first post on that rule.

You right, two post have the same mistake. I still confused x-rule-pre with pre-x-rule

P15 only work in x-rule-pre

@jmgomez:
These sorts of period-multiplying reactions are pretty commonplace, and can be used to construct guns of arbitarily high period.

Here is a simple example producing Gc at p408, using wildmyron's p24 gun:

Rebuilding the breeder with either of the two high-period guns built is left as an exercise for the reader.
