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

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.

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

And a surprisingly simple Pi => glider:

This uses just a block and 3 killer cells!

With these mechanisms, you can build what I like to call "Pi tracks".

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.

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?
