All that's needed to produce this boat-bit catcher is a little clear space with two blocks and a boat in it. So xs14_354c32ac shows up quite regularly as the final fate of these kaleidoscopes, completely out of proportion to its appearance in random ash.

Bill Gosper took an interest in these types of reactions back in May. Names for a couple of other possible final fates showed up during the discussion.

There's the Jedi Transparency Trick, where 90-degree block-glider reflections show up at the orthogonal axes of symmetry, and drill through everything in their way to reach the diagonal axes. That happens with the sample pattern below, at T=19659494:

Then there's the Jedi Bounce Trick, though that's actually not a final fate, but just a temporary stage along the way -- a 180-degree block-glider reflection that makes things a little more complicated for a while:

The resolution for that one is way out at T=35911778, by the way, with a classic boat-bit-catching eater built from another simple seed:

Code: Select all

#C A bo$obo$b2o boat has been seen in place of the beehive sometimes
x = 52, y = 52, rule = LifeHistory
.A$2.A$3A18$21.A$22.A$20.3A18$41.A$42.A$40.3A2$50.2D$49.ACA$48.D.D$
48.2D$42.A$41.A.A$41.A.A$42.A!

Almost 36 million seems like a pretty impressive survival time. It's the next best thing to random when one of these final-fate configurations is going to show up, though, so longer stabilization times should occur according to some kind of power law.

That means it should be possible to find, say, a 42x42 symmetric pattern that takes a really impressively long time to stabilize, just by testing lots of variants of the following pattern with randomly added symmetrical stable junk near the center (blue area -- too far inside the red circle won't make any difference):

Code: Select all

x = 42, y = 42, rule = LifeHistory
11.A.A14.A.A$10.A20.A$11.A2.A12.A2.A$13.3A10.3A5$16.10B$15.12B$.A12.

11.A2.A12.A2.A$10.A20.A$11.A.A14.A.A!
#C [[ VIEWONLY ]]

Without any junk this pattern stabilizes at T=16467511, generating an xs14_354c32ac boat-bit catcher again.

---------------------------------------

Seems as if adding aysmmetric junk in the center might even be an improvement on a line puffer as a source of unlimited novelty, or at least novelty that Golly won't be able to find an end to. With eight glider streams, the odds that all of them would simultaneously generate eaters or boat-bit stoppers seem very very low. Even if most of the eight streams are stopped, the remaining ones would be quite likely to drill through the center and liberate their opposite numbers.

All these patterns make for an interesting extended experiment regarding the drilling ability of a low-period glider stream. It seems pretty clear from watching these "collidoscopes" (not sure if that's a Gosperism or a George Maydwell-ism) that the average drill rate is positive at p768. That is, that a stream of gliders will eventually eat its way through pretty much any amount of random ash in its way, assuming that no eater or boat-bit catcher appears.

Note that this also makes cis twin-bees if the block is moved 7 spaces up. This is an interesting mechanism, but unfortunately, it doesn't improve the state of the art. The standard method (2 gliders each for the two blocks and the B heptominos) takes 8 gliders, and in January, Martin showed how to do it with 7 (i.e. 5 gliders make the engine and one of the blocks), and both mechanisms make trans twin bees by moving the block up.

The latest eater2 variant, xs24_0mm0mk453zc87011 is one I haven't seen before, at least from non-symmetric initial conditions:

I don't see a really good line of attack offhand, but does anyone recognize the chunk that I can't name around T=91, or the more immediate 9-cell ancestor at T=242?

This might be a fairly decent reaction if it could be converted to a slow-salvo seed, because the eater2 is backed right up to the eastern edge of its reaction envelope.

I really like the recipes that Catagolue comes up with, that start with a small number of cells that magically expand into a stable object with a larger number of cells.

I just happened to look at xs26_69b88c0siczx3553, for example, which grows from 18 cells to 26. It occurs relatively often due to variants of this reaction:

Here's a 10-glider-equivalent synthesis based on a slightly different R-bee source -- cobbled together before I saw the R-pentomino trigger variant, so it's probably not optimal:

I've recently been working on the next update to my web site, and I'll upload it when all the changes are made and working. One major change is that one can now directly search by agp/Catagolue names, and search results link to the corresponding Catagolue object page. I've also addressed bugs as they have been reported:

Extrementhusiast wrote:Main oscillators page (13-bit): jam is labeled as being P4
Main oscillators page (17-bit): Silver's P5 on carrier is labeled as Silver's P5 on snake (the actual Silver's P5 on snake is correctly labeled)

Main oscillators page (24-bit): P4 and P12 labels in image are swapped
Main oscillators page (24-bit): Merzenich's P10 is labeled in image and table as being unsolved, contradicting other parts of the site
Oscillators by period page (P10): dividing line in image is misplaced
Oscillators by period page (P12): wrongly states that no such oscillators are true P12 oscillators
Oscillators by period page (P276): size label in image colored as >1 glider/bit (when that should only be used for the cost label)
Exotic spaceships page (Caterpillar): wrongly stated that it was engineered in 2013, when it was actually completed in 2004
Flotillae page (4-SS): stated that Ecologist is Gosper puffer plus MWSS, but a LWSS is instead present in the image

Fixed.

Extrementhusiast wrote:Main oscillators page (17-bit): 199 has been typed twice

Fixed. I used to include fixed numbers in the HTML source, but it became harder and harder to maintain as lists kept changing size, so for most lists, I now include metacharacters that count the numbers of objects (i.e. the number of lines in the input file to the ZIP-file builder) instead. In this case, I forgot to remove the hard-coded number.

Extrementhusiast wrote:Main oscillators page (18-bit): French kiss is labeled as unsolved, contradicting other parts of the site (although the table and (unusually) the color of the image label are both correct)

Fixed. I had changed the color indicator, but not the number. For conformity, most of the stamp sections are separate files that are included in the main HTML file with #include, and the HTML files are run through a pre-processor. This way, if a stamp occurs in two places (e.g. 17-bit P3s occurs on both the P3 page and the 17-bit page), it only has to be maintained in one place - and if there are errors, they will occur in both places.

Extrementhusiast wrote:Oscillators by period page: oscillators of periods 23 and 41 aren't yet known (unless if there's something you aren't telling us!)

A few years ago, I was looking through the wiki and various other places to find out what periods were missing. For some reason, I seem to have thought that someone had recently (at that time) found periods 23 and 41, but I can find no evidence of it in my notes, nor on the wiki or anywhere else, so I was likely mistaken. Now corrected.

Extrementhusiast wrote:P3 oscillators page (22-bit): section is labeled as having five oscillators, when image shows six

Extrementhusiast wrote:P3 oscillators page (23-bit): section is labeled as having zero oscillators, when image shows one

Fixed. These are both a result of the automatic stamp-counting mechanism mentioned above; both the file lists were missing the newline at the end of the file, so even though the zip files were generated correctly, the line counting was off by one.

Extrementhusiast wrote:Main oscillators page (22-bit): Elkies's P5 is labeled in image and table as being unsolved, contradicting other parts of the site

This is not an error. While Elkies's P5 (20-bit) has been solved, and most larger stator variants can be derived from it, there are a few, like this 22-bit one, that currently elude synthesis. For object sizes 20-25 bits, I count 1, 1, 3, 5, 12, and 27 stator variants. Unique bases appear at 20, 22, 23, 24(x2), and 25 bits. I have also found some other unique ones at 26, 27, 27, and 28 bits. Of these, only the original 20-bit one, and the 24-bit one with the loaf currently have syntheses:

(UPDATE: you recently posted a synthesis for the 22-bit one, so that is now off the list).

Extrementhusiast wrote:Oscillators by period page (P10): 44-bit P10 labeled in table as taking 65 gliders (and in the P10 oscillators page, but not in the images in either case)

Fixed. 165 (the number shown on the images) is the correct number.

Extrementhusiast wrote:Double (skewed) eureka RLE: blocks aren't necessary

Fixed. I don't know why these blocks are there. My records show that you created the first 30-glider synthesis of this on 2013-10-07, and Matthias reduced it to 22 gliders on 2013-10-10 - and his synthesis included the extra blocks. They do, in fact form a pseudo-object with the oscillator, but as you point out, they are totally unnecessary. Removing the blocks also makes the synthesis of the skewed double eureka trivial, reducing it from 30 to 20 gliders:

Yes, I was also amazed to see those three results appear on the Twitter feed simultaneously!

Do we know which three 13-bitters are missing? One of them is the Sufficiently Long Snake, but I don't know what the other two are.

(I do have comprehensive lists of all small objects, so I suppose I could create a Catagolue page to display 'smallest objects not yet occurring naturally'.)

And, more importantly, when will we actually see a phoenix? Given its size, it seems well overdue.

There are already 39 soups that make a Phoenix (from the dates on the comments, all apparently uploaded within the past week): http://catagolue.appspot.com/object/xp2 ... 0602/b3s23.

You haven't looked properly. Those dots aren't black, which stands for a C1 soup.

Yes, I knew that, but it wasn't clear from any of the above messages that people were only looking only for C1 soups (or did I miss something?).

No, that one's new. I checked earlier today, and it wasn't there.
