What do you mean by "w/ dr and lls"? Did you combine them in some way?

I generated the partial oscillators with dr, and then instead of using JLS, I ran the background in LLS, and it gave me the still life (aka background) stabilization, and then I replaced the partial osc "1"s and "0"s with their corresponding foreground states.

Do you want the Python script that I used to convert partial osc to LLS state?

That makes sense. It's probably easier to create files for LLS to read than it is for JLS.

No thanks, I can see how it would work.

I guess it doesn't entirely count as "knowable" until a workable connection can be made to both the input and the output. The input is certainly accessible enough --

`#C sample BLx19R connectionx = 15, y = 28, rule = LifeHistory5.3D\$5.D.D\$5.D.D5.2A\$13.A\$2A9.A.A\$2A9.2A6\$13.2A\$7.D5.2A\$4.2B3D\$3.C2BD5B\$.3BC7B\$.3B2C6B\$3B2C6B\$.2BC7B\$.7B.3B\$3.B.B3.B2A\$3.B2AB2.BA.A\$4.2A4.B2A\$8.4B\$8.2A\$9.A\$6.3A\$6.A!`

-- but there's just not a lot of room around that pi output, and conduits starting with a pi input generally need lots of room. So probably a new transparent catalyst would be needed -- e.g., use one of the glider outputs to rebuild this ship, except it should really be something quicker and more direct than that:

`x = 31, y = 15, rule = LifeHistory22.2A\$22.2A2\$9.2A2.A\$5.2A3.3A\$5.2A4.A16.2A\$2A26.A.A\$.A27.2A\$.A.A\$2.2A\$6.2A\$5.A.A14.2A\$5.2A15.A\$15.2A6.3A\$15.2A8.A!`

Almost everything in Conway's Life is a novelty, so novelties are not interesting, regardless of whether they are known or not.

I meant is the reaction to produce the block known?

That's not quite what I'm reading as Freywa's implication. Freywa's post was triggered by Entity Valkyrie's question:

Entity Valkyrie wrote:Known??

The crystal and decay mechanism have been known for decades.

But this particular 180-degree reflection quite possibly has never been used before to restart crystal growth.

On the other hand, there doesn't seem to be any reason to learn this new variant, because it uses an unnecessarily complicated method of restarting the crystal growth. Here's Dean Hickerson's version from almost three decades ago -- also using two pipsquirter domino sparks, but in different positions from EV's version, which allows for a much cleaner restart:

`#N Crystal&decay 6600#C A p150 gun fires at a pair of pentadecathlons.  When the first glider#C hits the PDs, it is reflected back and hits the second, forming a#C honey farm.  Subsequent gliders form a crystal growing upstream.  When#C the crystal reaches an eater near the gun, it begins to decay.#C When it's all gone, the cycle begins again.#C The period of this pattern is 6600, but by moving the PDs, any period#C of the form  750 + 1950n  (n>=0)  can be obtained.#O Dean Hickerson, 3/27/90x = 96, y = 113, rule = B3/S235b2o\$5b2o3\$5bo\$4bobo\$3bo3bo\$3b5o16b2o\$2b2o3b2o15bobo\$3b5o11b2o6bo11bobo\$4b3o8b2obo2bo2bo2bo10bo2bo4bo\$5bo9b2o2b2o6bo9b2o5b2o\$24bobo8b2o3bo8b2o\$24b2o11b2o10b2o\$29bo8bo2bo\$4bo22b2o10bobo\$6b2o20b2o\$5b3o\$5b2o\$6bo\$5bobo\$6b2o\$20bobo\$20b2o\$2obob2o14bo2\$o5bo6bo\$14b2o\$b2ob2o7b2o\$3bo3\$35bo\$33b3o\$3b2o15bobo9bo\$3b2o16b2o9b2o\$21bo6\$20b2o\$20bo\$21b3o\$23bo26\$58bo\$59b2o\$58b2o16\$86bo6bo\$85b2o6b2o\$84b3o6b3o\$85b2o6b2o\$86bo6bo4\$79bo\$79bo2\$79bo\$78bobo2\$78b3o3\$78b3o2\$78bobo\$79bo2\$79bo\$79bo!`

So it's definitely not true that novelties are always uninteresting.

However, it's certainly true that new never-before-seen random combinations of known pieces are likely to be uninteresting, unless they solve some problem in a better way than any previous pattern -- smaller, faster to recover, lower population, lower period, or basically whatever criterion you want to advertise.

If a pattern is not any kind of improvement over existing technology, then "Known??" is just not a very appropriate question.

Well, that pattern IS an R-pentomino predecessor, so that is a very tight R-pentomino grandparent eater that likely can never be used. Still.

A good exercise would be to try to find any way to get that R-grandparent into that position in the first place, without having previously interacted with the loaf. It's possible to do, but not easy.
