Nice work! However, the constructor requires a snake to be inserted in to function, which makes it a little hard to move around. Here's my horribly complicated attempt to make one that doesn't require the extra snake (repeat time 29): x = 25, y = 11, rule = SnakesNLadders 17.D2.D$16.D$20.D$16.D7.D$....

It is not interesting enough to merit its own LifeWiki page (we now have 16*16 soups that last thousands of generations longer), but I think it's left up for historical reasons (sort of like Flying Wing). @XxAlphaHexagonxX: What part of that reaction strikes you as interesting? The only thing I can ...

While it is unfortunately true that a nonexplosive rule cannot be created with those ships, it is highly likely that a stable one exists in the same general area with some different ships. Keep searching!

(side note: it is generally advised to trim long quotes so they don't take up as much space)

Here's a useful script for this sort of thing. You give it a pattern and it will find all rules where it behaves exactly like the original rule for a given number of generations (this version doesn't use minus signs). # Rule computation script for use with Golly. # Author: Nathaniel Johnston (nathan...

In the renowned American diplomatic style, the war has been ended by dropping a nuclear bomb on the former republic of BokaBB.

A more "efficient" (or at least simpler) algorithm/procedure/method/whatever involves enumerating all single-channel recipes by binarily counting, except that you carry a 1 whenever another one is 13 digits or less behind it, with 1's representing gliders. (one digit to the left is 1 digit further a...

Is this a proof of concept or is there a 16-glider collision somewhere that makes this binary slow salvo? If it's the former, it makes more sense to look for an example before attempting to show how it could construct universally.

Using 3 gliders in the rectifier loop, we can get 8n+6 for n≥19 (lowest period is the disappointingly high 158): x = 101, y = 79, rule = B3/S23 8bo$7bobo$8bo2$6b5o$5bo4bo20b2o$4bo2bo23bo$bo2bob2o21bobo$obobo5bo18b 2o$bo2bo4bobo7bo3bobo$4b2o2bo2bo5bo2b2obobo$9b2o9bo3bo$16bo23b2o$16bo 2bo20bo$15bo2b2o...

An actual fun fact: A lot of names have really interesting origins. For example: Dukljan, the Croatian folk demon, is derived from the Roman emperor Diocletian, who was infamous for persecuting Christians. Or cologne (male perfume), named after the city, which comes from Roman Colonia (colony), whic...

Because I love being super pedantic, let me point out that the slowest explicitly constructed spaceship in Life is the Camelship , which travels at about 240m/s which is less than the speed of sound. (embarrassingly, I had to look up the speed of light) The slowest explicitly constructed spaceship w...

Crossposting the rule 110 replicator from here : x = 3, y = 2, rule = B2ei3aci4aei5kqr7e/S01c2-kn3ijry4citwy5aeiq 3o$obo! There's probably a version with puffers or a small ship or some other thing that allows us to make really interesting things. Naturally, we can make oscillators (yes, you can tri...

This is the basic 2c/3 Blinker fuse.

Welcome to the forums!

The Overweight spaceship is known, as are ways to stabilize it. The wiki page does not mention this, but it can be supported with a fixed width as well: Do we have some updated answers to this question? It will make its way to the OWSS article. E.g. width 31 possible: x = 29, y = 113, rule = B3/S23 ...

Here's a 90° turner/and gate in B01357/S012 which should work in all rules with self-hassling replicators: x = 592, y = 363, rule = B01357/S012 362bo$363bo96$362b2o6$361bo2bo6$361bo2bo6$361bo2bo6$361bo2bo6$361bo2bo 6$361bo2bo6$361bo2bo6$361bo2bo6$361bo2bo6$361bo2bo6$361bo2bo6$361bo2bo 6$361bo2bo6$36...

Regarding puffers, my suggestion would be to either call non-stabilizing puffers something like "non-stabilizing/non-periodic/exploding/chaotic puffers" or just don't even both putting them into the puffer category. Why do they need to be called puffers anyway? The biggest objection to calling them ...

Apologies if you people on the Discord have figured it out already, but here's a general plan for a potential mini (but with a huge orthogonal bounding box) demonoid (with the blocks probably farther apart and the snakes closer): x = 38, y = 32, rule = B3-cy4ik5aeiq6k7c/S2-k3-ciqy4itwyz5-cjry6kn 8bo...

The second pattern is basically an ordinary rule 90 replicator except that it moves. If you move each of the preblock units back 6 diagonals every 12 generations, you will see that it is fundamentally the same type of pattern.

The Sierpinski triangle is the history of the simplest replicator (such as the one in B2a/S), so naturally most puffers of replicators (such as the first pattern) make them (each row of replicators further behind the puffer shows the next layer of the triangle), as do replicating puffers (the replic...
