I'm now getting errors saying "global name 'set' is not defined". I'm not very familiar with python, but I've looked around a bit and have seen 'set' related errors due to use of python 2.3 (apparently a change was made in 2.3.1). What version of python are you using? The current version is 2.6.4, ...

Could someone who has a working copy of the script attach it to their post? I keep getting syntax errors. Lines 110 and 111 of Nathaniel's code are insufficiently indented (both lines need five more spaces of indentation). Here is a copy of the script that should work: # A simple Python census scri...

Here are oscillators of periods 5, 6, 7, 8, 9, 10, and 15 found by random agar search. I have not searched very long, so there are surely more to be found in this way. x = 109, y = 71, rule = B3/S01367 bobobo21bo31bobobo12bo7bo$o57bo5bo$14b2o11bo49bo5bo16bob2obo$o26bo30bo 5bo8bo4b2ob2o4bo10bo8bo$12b...

I have been reducing the stators of many of the period 5 oscillators in the collection using WinLifeSearch (which is somewhat tedious). Here are my results: x = 113, y = 28, rule = B3/S234 2b2o$2bo3b2o16bo37b2o23bo$obo4bo15bobo15bobob2o14bo23b3o$2o20bobobo14b 4obo14bobobo15b2o2bo17b2o3b2o$bobo18bo3b...

Here is a collection of every oscillator found by either me or others on the forum.

I've been using WinLifeSearch to look for small low-period (3-6) oscillators. I've found some 14 cell p3 oscillators, as well as a 14-cell p4 oscillator. I haven't found any p5 oscillators that are smaller than the 18-cell oscillator found by Lewis, but I have found a 15-cell p6 oscillator, which is...

There was no p46 included with the files. Sorry, I missed that one. Here it is with a finite stator: #C Non-trivial p46 oscillator x = 30, y = 30, rule = B3/S234 13b2o$13b2o2$13b4o$9b2obo4bob2o$10bobo4bobo$10bobo4bobo$7b2obo8bob2o$ 7b2obo8bob2o$4bo5bob2o2b2obo5bo$4b7obo4bob7o$12bo4bo$4b3o2b3o6b3o2b...

How were the oscillators found? Which programs were used? I was using a random agar search under various symmetry types. Since patterns in this rule tend to spread into large areas of stable cells with small pockets of activity, billiard tables can usually be picked out. I have attached the oscilla...

This rule provides a large area for high-period billiard table searches. I have been trying to fill some of the holes in Lewis' oscillator collection. x = 54, y = 231, rule = B3/S234 7b2o3b2obo$7bo4bob2o23b2o$8bo7b2o21b2o$7b2o7bo$17bo21b4o$7b2o7b2o20bo 4bo$7bo4b2obo19bo2bo4bo2bo$8bo3bob2o18bobobo4bo...

here's the only recipe I can find for creating the pair of Snakes Here is a direct 8-glider synthesis of two snakes from Mark Niemiec's site: x = 17, y = 15, rule = B3/S23 4bo$2bobo$3b2o11bo$10bo3b2o$10bobo2b2o$3bobo4b2o$4b2o$4bo7bo$11b2o$5b 2o4bobo$2o2bobo$b2o3bo$o11b2o$12bobo$12bo!

Domino + 2 snakes = Pseudo still life. That isn't a pseudo still life, as the 11-cell inductor is dependent on the snake for stabilization. It is also unnecessary to use a domino spark in that position, as a single-cell spark in a more accessible location has the same effect: x = 37, y = 16, rule =...

Fuses can also crawl up glider waves in various ways: #C glider wave fuses by Nicolay Beluchenko and Mitchell Riley x = 223, y = 223, rule = B3/S23 213b3o3b3o$199bo12bo2bo3bo2bo$198b3o5b3o6bo3bo$197b2obo5bo2bobo3bo3bo$ 38bo16bo141b3o6bo2bobo3bo4bobo$37bobo14bobo140b3o3b2o10bo$36b2ob2o12b 2ob2o139b3o...

One rule to note would be 2/2. It is easy to see why 1-cell thick walls cannot be destroyed. Indeed, although it should be noted that the indestructibility of it is dependent on the two rows of dead cells surrounding the row of live cells. Unfortunately there is no way to make such a pattern that i...

And this construction of [14.22]... It would be nice to reduce the construction, but I'm not sure if that's possible from what I posted above. At any rate, it has only occurred once in my searches and so must be quite rare. Also, does anyone have Buckingham's glider syntheses of still lifes? (I wou...

Just as clarification, that is not a polyomino, as not all of the live cells are orthogonally connected. Also, it's standard to use the Greek hept- prefix rather than the Latin sept- when describing polyominoes (Pi heptomino, B heptomino, etc.). (Tetris = quadris?)

Are you referring to the tracks along which superstrings travel? I'm fairly certain that the term waveguide also refers to any other wave stabilization. As for the superstring waveguides, I think the tub and boat versions are the only clean ones known. Other (dirty) waveguides, however, can be creat...

Here are some partial fumarole syntheses found by Jason Summers and Stephen Silver: x = 212, y = 108, rule = B3/S23 89b2o4b2o71b2o6b2o$89b2o4b2o45bo8bo16b2o6b2o$115bo8bo18bo6bo17b2o6b2o$ 5b2o14b2o91b3o6b3o18bo4bo$4bo2bo12bo2bo65b3o2b3o17b4o4b4o19b4o19bo8bo$ 5b2o14b2o67bo4bo21b2o2b2o44b3o6b3o15b2o6b2...

Are the lists on the site still updated? Yes, they are; I have been checking the statistics semi-regularly just out of curiosity, and they are still being updated (the rate of new methuselah discoveries has greatly decreased, however). Amazingly, over 1,000,000,000 soups have been censused in Conwa...

Very nice! I've updated the wiki gun page accordingly.

I did not think it feasible to get three gliders from colliding two of the engines. The gun construction is very impressive; I don't know how you do it!

You are missing the top part of that pattern file. The pattern file is too large to be posted directly in RLE format. I've attached the complete oscillator to this post in a ZIP file. As to making a gun, I can only imagine one would need to produce two glider streams from one side of the debris cre...

I've been wondering whether some large oscillators composed of smaller components are synthesizeable. The ones I've looked at recently are the following p14 and p36 oscillators: #C p14 and p36 x = 207, y = 172, rule = B3/S23 150bo$150b3o$153bo$152b2o5$26bo6bo$20bo5b3o4bobo$19bobo7bo2bobo129b2o$ 19bo...

Here are some methods of oscillator construction found by Jason Summers. Some of these have been turned into syntheses, and some of them have not: x = 1054, y = 381, rule = B3/S23 60bo8bo248bo$38b2o19b2o8b2o248bo6b2o$3bo8bo25b2o18bo2bo6bo2bo245b3o6b 2o330bo$2bob3o2b3obo44bobo8bobo586b2o$3bo2bo2bo2bo...

This topic is for the discussion of glider syntheses and glider synthesis techniques. New glider syntheses, as well as improvements to old glider syntheses should be posted here. Glider synthesis resources: • Glider constructions at Game of Life info • Mark D. Niemiec's Life Page • Glider syntheses ...

I think we should probably go over the various naming "rules" that have been created and see what we can learn from that. There are certainly problems with the current naming conventions, especially concerning still lifes and period-2 oscillators. Also, I don't think currently established names are ...
