What is e9jp?
My opinion about E9jp.

E9jp's abbreviation should simply be E. While E is often used for E-heptomino, E-heptominos are less useful than E9jp. While it is not common, E9jp is used in the smallest 180 degree reflector, H-G with lowest repeat time, F H-H conduit with lowest step and highest clearance block factory (That is safe). Thus, E9jp should be E - over the sole criteron of utility (Like H used for the Herschel instead of H-heptomino.) Moreover, more E9jp conduits are known than Dove, Blonk-tie or I-heptomino conduits! (JJ is too confusing - J is the blonk-tie, so a hypothecal JF154JJ could mean the 11th JF154J! Trust me, we will have lots of these problems in the future if JJ is used.)

"E" is already used for the E-heptomino, which is present in recent updates of the ECC viewtopic.php?p=164613#p164613

Can you explain where the number 11 comes from?
"JF154JJ" unambiguously reads as a conduit that takes 154 ticks to transform "J" into "JJ" while keeping the orientation unchanged.
(Likewise, if "LT" is used instead, then e.g. "LTBx199B" would be a conduit with input "LT", output "B" appearing after 199 ticks, and output orientation "Bx".)

A space cleaner was originally meant to be any pattern that lives in an agar, constantly eating through this agar in all directions simultaneously on its border, leaving empty space inside. Examples involve my ancient block agar cleaner (from 1993?), but also the more recent space cleaners that Keith Amling constructed for the zebra stripes agar.

So in some sense it is the opposite of a space filler that builds an agar out of empty space.

When I run my version of PlutoniumSearch on B2cei3ai4cj7/S12-ak78, it gives p135s, p144s and p603s which don't seem to actually be it. Is this intended behavior and how do I fix it?

Can you provide enough details to be able to repeat the same search that produced unwanted results?

You may want to use g.getrule() and/or g.setrule() (see Golly Help -> Python Scripting) instead of "rule = g.getstring...", to avoid entering the rule manually and to make sure that Golly is set to this rule.

Oh, it seems like I forgot the g.setrule part. But if you add it in, and use slice 1(and default settings), you should be able to reproduce the bug.

I got the following "p135" which is not actually a p135:

Code: Select all

x = 8, y = 8, rule = B2cei3ai4cj7/S12-ak78
7bo2$5b3o$obobo$obobo$5b3o2$7bo!
I put the above pattern in Golly and ran a script[1] that computes hash values of successive generations. My script gave this message:

Code: Select all

T = 638 and T = 503 hash to -139953102
Note that 638 - 503 = 135 which explains why the pattern was incorrectly classified as "p135". It's due to a hash collision.
To avoid/reduce hash collisions, one would need to modify the searcher to include more information about the pattern in the key (e.g. population, bounding rectangle).

[1]: Here's my script I mentioned above:

Code: Select all

import golly as g

d = {}
for t in range(10000):
   _h = g.hash(g.getrect())
   if _h in d:
      tt = d[_h]
      g.note("T = {} and T = {} hash to {}".format(t, tt, _h))
   else:
      d[_h] = t
   g.run(1)

Why does the dove have a special role in conduits even though only 3 conduits are known with it as an input (and all output a glider, which can be easily obtained another way). Many other common active regions look more promising than this one, yet none of them get on the list of conduit active regions.
Currently writing a utility in Lua that may be helpful for faster manual pattern manipulation.

The "D" column in MathAndCode's update of ECC contains more than 3 conduits: viewtopic.php?p=164613#p164613

I just posted in another thread a track involving this active object:

ECC lists a CFx115D converter that can be followed by the eater posted above, and can be preceded by PL328C. The other direction (a track that begins with a D and ends with a H) is possible by replacing the top block with an eater 1 and appending a glider-to-Herschel converter.

Technically yes, since Cordership-to-glider and glider-to-Cordership converters are known, so you can just string them together.

Realistically no, since a lot of people wouldn't really want to call an engineered monstrosity like that a reflector. Among other things, two-engine Corderships aren't mirror-symmetric, so along with color-changing and color-preserving "Cordership reflectors", we'd also have chirality-changing and chirality-preserving variants.

Another way to say it: in a literal sense the current LifeWiki definition of "reflector" supports the idea of a Cordership reflector -- but if you look at current usage, nobody ever tries to talk about "reflecting" big awkward things like Corderships, or even smaller asymmetrical spaceships like loafers. Reflection stops being a useful concept somewhere in there.

Are there any fuses involving this arrangement of beehives ?

How did you arrive at this oscillator?

It is listed in Mark Niemiec's database as "28-bit P8 #1" with a 25-glider synthesis, found in 2013 viewtopic.php?p=9792#p9805
Edit: listed as 28P8.2 on pentadecathlon.com
b3s23osc lists the oscillator without discovery information (unless I'm mistaken it was added in this commit in November 2021).

It doesn't have a name. It's just blind luck that it happens to be in three oscillators (the others being 45P25 and Raucci's p102); it's not that common.
