The "Gray Cells" in LifeHistory Rule

[rattlesnake]

Another stator reduction:

Code: Select all

x = 3, y = 2, rule = LifeHistory
AB$2AF!

[qqd]

Another stator reduction:

Code: Select all

x = 3, y = 2, rule = LifeHistory
AB$2AF!

The rotor is already known. My stator version supports the rotor in a different way, however.
Here's a related oscillator:

Code: Select all

x = 6, y = 8, rule = LifeHistory
4.2A$5.A$2.F2A2$2.A$.A.F$A.A$2A!

EDIT: B-to-2G, with both gliders on the same lane. They are separated by 37 ticks, though, so I don't know if this will be useful:

Code: Select all

x = 12, y = 9, rule = LifeHistory
A$2A$.2A$2A9.F2$3.F3$9.F!

By the way, is anyone maintaining an oscillator stamp collection for this rule?
Also, I think a B should be the standard active region for conduits, as Herschel conduits tend to have transparent blocks, and also because of this starting reaction for almost any B conduit, which produces an extra glider:

Code: Select all

x = 4, y = 6, rule = LifeHistory
A$2A$.2A$2A2$3.F!

Here is a sample B-to-C-to-B conduit using that reaction:

Code: Select all

x = 16, y = 14, rule = LifeHistory

EDIT2: A p78 glider gun based on a p78 B-factory:

Code: Select all

F!

Using my B-to-2G, we can create an computerless irregular glider gun without any computational circuitry:

Code: Select all

x = 34, y = 26, rule = LifeHistory
28.F2$33.F6$30.F7$F3$30.F$20.A$F16.5A8.F$22.A$20.2A$2.F16.2A7.F$7.F
10.A4.F$11.F7.F!

The spacings between gliders alternate between 37 and 41, if I am not wrong.
EDIT3: A p156 century hassler, using a C-to-C conduit consisting of only a single killer cell. Also, it only interacts once to remove a single cell, so sparkers from ordinary life might be able to do the job, perhaps producing the first p156 century hassler in ordinary life:

Code: Select all

x = 19, y = 19, rule = LifeHistory
6.F6$18.F2$13.3A$12.A.A$12.2A2$F6$12.F!

Coincidentally, 156=78*2, so here is one way to perturb the p78 glider gun using the hassler:

Code: Select all

x = 35, y = 48, rule = LifeHistory
22.F6$34.F2$29.3A$28.A.A$28.2A2$16.F6$28.F12$30.F7$F3$30.F$20.A$F16.

Is someone maintaining an oscillator stamp collection for all patterns with killer cells?

Putting four copies of it together produces a p728 four-barreled gun, and so this is one of the few known B conduits that don't delete their gliders with their killer cells if used repeatedly:

Let's revive this thread, starting with F52, a new B-to-B conduit consisting of just 2 killer cells, and releases a glider:

Code: Select all

x = 10, y = 6, rule = LifeHistory

It can be chained, and the gliders aren't removed by any killer cells:

This allows for extending some of our B tracks, as well as converting them into guns. Here is a p1200 eight-barreled glider gun, obtained by inserting 12 F52s in my p576 B-track, and whose envelope looks like a waffle:

I find these cells to be fascinating. A bit of tinkering around found me this:

Code: Select all

x = 9, y = 5, rule = LifeHistory
F7BF$.2B3A2B$2BA3BA2B$.B2AB2AB$F.5B.F!

This moves a house forward at 6c/17.
I also found a 90 degree turner:

Code: Select all

x = 17, y = 14, rule = LifeHistory
10.F$F.B.F2.B.3B$4B2.7BF$16B$15BFB$17B$15BFB$16B$4B.11B$F.B.F.F7BF$7.
2B3A2B$6.2BA3BA2B$7.B2AB2AB$6.F.5B.F!

Plus a duplicator:

Code: Select all

x = 17, y = 59, rule = LifeHistory
4.F7BF$5.7B$4.F7BF$5.7B$4.9B$5.7B$4.F7BF$5.7B$4.F7BF$5.7B$4.9B$5.7B$

5.7B$4.9B!

And a surprisingly simple Pi => glider:

Code: Select all

x = 9, y = 16, rule = LifeHistory
F.5B.F$.B2AB2AB$2BA3BA2B$.2B3A2B$F7BF$.7B$F.5B.F$.7B$9B$8B$7B.F$B3.B$
3.3B$3.B2AB$4.2A!

This uses just a block and 3 killer cells!

With these mechanisms, you can build what I like to call "Pi tracks".
Here's an example:

Code: Select all

x = 131, y = 138, rule = LifeHistory

Thsi is a large version of a p188 glider gun - I know it can be condensed.
If anyone has found any of this before, well, kudos to them.

And could any of these be condensed?

this reminds me a lot of sticky. the gun you showed is equivalent to this pattern in sticky

Code: Select all

x = 7, y = 7, rule = Sticky
7A$ACB2.CA$A.3ABA$A.3A.A$AB3A.A$AC2.BCA$5A.A!

(tube lengths are not equivalent)

this means that patterns in sticky that do not use a small set of mechanisms (including the slide mechanism) can be recreated in lifehistory.

[tommyaweosme]

extensible period 2 oscillator 2 transitions away from lifehistory

Code: Select all

x = 10, y = 5, rule = B3/S235i8History
.8F2$10A2$.8F!

[confocaloid]

extensible period 2 oscillator 2 transitions away from lifehistory

Code: Select all

x = 10, y = 5, rule = B3/S235i8History
.8F2$10A2$.8F!

Actually, that's an oscillator in a [R]History multistate extension of a 2-state cellular automaton that's 2 toggled isotropic living conditions (both of which in this case are survival conditions, not birth conditions) away from Conway's Life.

More cellular automata have been "2 transitions away from lifehistory" than that oscillator has. Not only is that unacceptably nonsensical; worse, it's also vague, allowing for various rulesets such as "LifeHistory except a state-2 cell becomes state-0 in the next generation, unless it's currently surrounded by eight state-0 cells":

Code: Select all

2, 0,0,0,0,0,0,0,0, 2
2, x1,x2,x3,x4,x5,x6,x7,x8, 0
# old rules go here

That's literally two added transition rules away from LifeHistory. Did you mean to include that possibility, or to exclude that possibility?
