Does anyone know anything about this oscillator?
x = 9, y = 7, rule = B3/S23
5bobo$o4bo2bo$ob2obo2bo$o$2bo2b2obo$b2o4bo$b3o3bo!

I'm aware of smaller oscillators, both in cells and bounding box, but its size is fairly small, so someone should know about it.

Hi, first post here, think i came up with something, its a small period 15 oscillator.
#CXRLE Pos=1,1
x = 3, y = 16, rule = B3/S23
bo$obo3$3o$3o$bo3$bo$3o$3o3$obo$bo!


I couldn't find anything about it, so... did i find something new?

EDIT: never mind, realized it's a pentadecathlon. i was confused because the wiki showed it sideways and i had it vertical.

I found a 10 cell scorpion predecessor. Or probably I rediscovered it...

I noticed something interesting about this pattern. Between generations 275 and 279, a loaf on the lower right gets flipped 180 degrees by what I believe is a somewhat common blinker predecessor. I know other examples of loaf rotation exist but I think it's still worth pointing out.

I'm not sure who first discovered it.

On a related note, when you are looking for perturbations of the honeyfarm + eater combination, are you also considering other seed still lifes (besides the block)?

Yes - beehives and boats can trigger the honey farm explosion too:

I think the block is the most promising seed because it's the most common of the three, but I get just as excited when my searcher finds a boat or a beehive in about the right place.

There are two different patterns for LWSS, each requires 6 blocks.
Not sure if any of these have been discovered or if the number of blocks required can be lower.

Very nice! I don't think there were any known pure-Blockic spaceship recipes until now (except the obvious expensive ones, splitting and synchronizing two gliders aimed at a block).

I just spent a few minutes with Paul Chapman's new Seeds of Destruction applet, and came up with a tighter variant of the MWSS seed:

x = 37, y = 19, rule = B3/S23
28b2o$28b2o3$10bo13b2o$11bo12b2o$9b3o8$4b2o29b2o$2o2b2o29b2o$2o$18b2o$
18b2o!

I'm hoping I can save a block on at least one of the four original recipes, since they all use three blocks for the cleanup -- the basic "dirty" recipes are just three or four blocks:

x = 275, y = 30, rule = LifeHistory
263.2A$263.2A$167.2A$167.2A$94.B$93.B.A$93.ABA177.2A$94.2A155.2A20.2A

Here's a 6-block seed that produces a couple of output gliders as well as an LWSS. Not that that's any kind of improvement -- things like this must be a dime a dozen. It's the 5-block (and 4-block?) seeds that seem to be the rare gems in this search space.

x = 62, y = 42, rule = B3/S23
bo$2bo$3o14$34b2o$34b2o12$19b2o$19b2o39b2o$60b2o4$52b2o$52b
2o3$52b2o$36b2o14b2o$36b2o!

Here's an oddity, also generated by the Seeds Of Destruction game: a three-block slow glider-pair reflector!

x = 195, y = 140, rule = B3/S23
o$b2o$2o12$141b2o$137b2o2b2o$137b2o8b2o$147b2o18$96b2o$96b2o5$94b2o$

121b2o2b2o$121b2o!

It doesn't keep the spacing between the gliders constant, obviously, but you can't have everything... It can be hooked up to itself to make a reasonably efficient Blockic delay circuit for a single glider:

x = 137, y = 126, rule = B3/S23
83b2o$79b2o2b2o$79b2o8b2o$89b2o50$bo$2bo$3o2$11b2o$11b2o4$15b2o$15b2o

2b2o$63b2o!

Probably quite useless, except for very odd situations in self-destructing circuitry, but fun to watch.

Also there's a G+2B4 megaspark reaction that allows for a simultaneous existence test for three blocks. If you add a block at the spark's edge in any of three locations, you get a glider out -- and none of the outputs interfere with each other:

x = 218, y = 94, rule = LifeHistory
171.A$172.A$170.3A15$.A39.A39.A39.A$2.A39.A39.A39.A$3A37.3A37.3A37.3A

12.2E38.2E38.2E38.2E!


A few more blocks also gave me my first new Blockic LWSS-producing reaction (right side, above), though it doesn't seem to be competitive with knightlife's 6-block recipes.

Short summary: the Seeds of Destruction applet seems to be able to reach a huge amount of new search space -- anyone who enjoys crashing gliders into things should give it a try!

There is a 2-block seed that makes an LWSS with plenty to clean up:
x = 20, y = 21, rule = LifeHistory
12.2A$12.2A3$2A$2A13$17.3A$17.A$18.A!

I think the above has probably been found before because it has just two blocks.

Add one more block:
x = 20, y = 41, rule = LifeHistory
16.2A$16.2A19$12.2A$12.2A3$2A$2A13$17.3A$17.A$18.A!

Now you get two LWSS from just 3 blocks, but quite a challenge to clean up. As a Blockic seed it would still be a record if it took a total of 11 blocks to make the two LWSS since so far it takes 6 to make one LWSS.

Edit:
7-block seed makes 3 LWSS:
x = 46, y = 44, rule = LifeHistory
2A$2A$28.2A$17.2A9.2A$17.2A11$44.2A$44.2A7$13.2A$13.2A2$30.2A$.2A27.
2A$.2A13$18.3A$18.A$19.A!

Still far from clean...

Many times, no doubt! I rediscovered it using the applet yesterday, and sent the pattern along to Paul as a possible "unsolved puzzle" to add (how to clean up with three blocks or less).

Oddly enough, I also stumbled on that pattern yesterday -- the applet seems to make it fairly quick to find the good stuff, even though the only filter so far is the exact same neural net that MikeP used to discover the Snark:

MikeP wrote:This stage of the search selects interesting partial results using a classifier based on a neural network of approximately 10^11 nodes which was generated using a genetic algorithm over a timespan of several hundred million years.

knightlife wrote:7-block seed makes 3 LWSS...Still far from clean.

You can say that again! With that big a cleanup problem, you almost might as well go for broke and try cleaning up one of the obvious composite 6-block seeds that makes an LWSS in all four directions:

x = 81, y = 41, rule = B3/S23
16b2o$16b2o18$79b2o$12b2o65b2o$12b2o2$59b2o$2o57b2o$2o10$55b2o$55b2o2$
17b3o$17bo$18bo!

But from the standpoint of collecting good new Blockic tools, a multi-LWSS seed may set technical records, but the single clean Blockic seeds are going to be a lot more useful...!

There are four pi+block reactions that output a LWSS (no M/HWSSes). The one just posted is indeed the cleanest and fastest; the next smallest already seems much less viable for cleanup.
x = 13, y = 12, rule = B3/S23
bo$3o$obo8$11b2o$11b2o!


I also know of one reaction to produce a temporary LWSS (the block can be shifted down one cell with no difference) which might be releaseable.
x = 28, y = 5, rule = B3/S23
bo$3o$obo$26b2o$26bo!


There are a bunch of faster and mostly cleaner pi+blinker reactions though:
x = 15, y = 15, rule = B3/S23
12b3o12$bo$3o$obo!

x = 20, y = 6, rule = B3/S23
bo$3o$obo3$17b3o!

x = 6, y = 20, rule = B3/S23
5bo$5bo$5bo15$bo$3o$obo!


Also, a very fast pi+blinker+beehive reaction yielding a MWSS, but the pi here cannot be derived from block+glider (alas):
x = 6, y = 14, rule = B3/S23
3b2o$2bo2bo$3b2o4$bo$3o$obo5$2b3o!
