Oh...so it's unknown if it's unknown(sorry for the tautology)

To add to this, the reason we know
exactly how many 22-cell still lifes exist is that they have all been found by computers. In fact, all still lifes up to 24 cells have been enumerated, so any still life with 24 or fewer bits has definitely been "seen" before.
Still lifes are very easy to find using search programs or just testing by hand. They aren't considered interesting unless they do something or have some special property.
This is covered under
rule 4.

You can sort of preserve it with an eater (but can it be turned into some sort of conduit?):

Yes. This is 22.16278. You can even look it up via image search on my extended pattern search page (
http://codercontest.com/mniemiec/lifxsrch.htm), which is like my normal search page, but also also adds (without syntheses) lists of all still-lifes up to 18 bits, and all symmetrical ones up to 24 bits.
I have never bothered posting the full collections of larger-sized still-lifes anywhere, as they are huge, and few people would have need of them. Anyone who DOES have need of them would probably make better use of them in some machine-readable, rather than human-readable format.

I think the reason why it's called a hebdarole is the spark at the top and it being likened to the fumarole. Replace that and its namesake is gone; no point in calling it a hebdarole anymore. So while using two copies of the bottom is obviously smaller, putting that on the wiki would have no purpose.

Very strange! I think that is actually new. At least, it's not in the R-to-B collection, presumably because the B that you get out can only be processed by a particular chainable component.
So that eater allows an R input instead of a B input, for a number of related conduits:

Yeah, but that's before you switch over to the oblique B stage. Lots of things work with the BRx46B, but only a few B-to-Gs work after you start a chain of limited-BF78B (I think). I'd really like there to be a workable Spartan B-to-X that attaches to BF78B, in particular, where X is not a glider... but I think it would have to be a Silver G-to-H attached to a G output.
If you run a BF78B into a BFx59H (=Conduit 1), or most other B-input conduits, it almost works, but unfortunately leaves a toad behind:

Queen Bee phase shifting. There's slight possibility that we could make it to a p26...

I found a similar reaction, with a completely different start:

The difference between Scorbie's reaction and yours is that his involves a
queen bee interacting with two
blocks and the result is a queen bee how it would look like but 2 generations later if not these two blocks (by the way, I think I saw this pattern before.) Yours is quite a random pattern, resembling traffic lights with some garbage inside, that would be problematic to find use of. There are infinite number of queen bee predecessors, and they can't be all interesting.

Speaking of queen bees, you can make them from honey farm predecessor:

I pasted a Q-pentomino over its product. I couldn't find anything on it in the wiki (I searched in

Unrelated to my previous post: Is this glider gun glider collision known?
Code: Select all

It looks like two gliders pass, then one glider is turned into a block and destroyed while two more pass (infinitely repeating pattern.)
P.S. I typed out the RLE for this manually, since I don't want to take the risk of downloading things.
(Man, typing out that RLE took far too long!)

A lot of what is called "p30 technology" uses reactions like that to filter the glider streams from a gosper gun into desired patterns of gliders and missing gliders. Many such reactions are known. Look up "triller's p30 thread" for some impressive constructions based on p30 technology.
Regarding your earlier post: If something isn't on the wiki, it could be that it is new and exciting, or it could be that it is boring and doesn't deserve a wiki entry. Beginners often don't have the intuition for which is which, and certain wiki categories can give the wrong impression. Generally, still lives, methuselahs, etc. are boring. Predecessors of common active patterns (like the queen bee, which was your first post) are also boring by the wiki standards. But this thread and the useless discoveries thread are good places to learn and get that intuition.
Regarding unwillingness to download programs: I'm not sure what your internet experience is, but if you are brave enough to download Golly for game of life things, you won't be disappointed. Among other things, you can highlight a part of a pattern and copy it to clipboard, where it can be pasted later as an RLE. It is impressive that you type out your RLEs but it will be so difficult to make new discoveries if it takes that much effort just sharing them.

Additionally, at least two of the creators of Golly post relatively frequently on this forum (usernames "dvgrn" and "Andrew").
As a further safeguard, Golly is not all that high on the popularity scale, so it would be an unwise use of time for a hacker to insert malicious code into Golly, as the number of people affected would be relatively small.

To be honest, I kind of have to get permission before downloading things. If I don't, well, it just brings me embarrassment.
It's almost always a hassle to get permission, so I don't even try.
Besides, I can just do tests directly using the "Preview" button, and if I think I've found something interesting and want to post it, I can just press the "Submit" button.
That being said, I usually just start by going to http://www.cuug.ab.ca/dewara/life/life.html.
(I'll probably get faster at making those RLEs; yesterday was my first time trying to make one.)

A pair of blocks can eat a LWSS:
Code: Select all
x = 12, y = 7, rule = B3/S23
9b2o$9b2o2$o2bo$4bo5b2o$o3bo5b2o$b4o!
This seems like it ought to be well-known, but I don't think I've seen it before. It showed up spontaneously in a large pattern that I was running.
Has anyone seen it before?

This reaction can be found in Jason Summers' jslife pattern collection under the "misc" folder as part of the file "ss-eaters.lif". It doesn't give a discoverer or date of discovery.

Now this is almost slightly interesting:
