EDIT: Blinkerspawn and I have been working on some results derived from the above in the discord, and have determined that the p6 and 8 agars are both embeddings of stripe oscillators into the form of phoenix agars. (specifically,
they're a simple background pattern XORed with the specified stripe patten). So any wolfram rule 18 (which describes the behavior of those stripes) spatially periodic even-length oscillator in which all on cells have equal spatial parity (that is, the distance between any pair of on cells is even) can be converted into a cgol phoenix agar of the same period.
(Underline mine) The background pattern, by the way, is the barberpole oscillator.
Been in the discord, was interested in the topic.

I think I got it:
This p8 (See AGreason's post above)
Code: Select all

Behaves like this W18 pattern, right? [code deleted, cause read below]
Edit: Technically yes, but just thinking it as
Code: Select all
x = 8, y = 17, rule = B3/S:T8,24
8o16$8o!
is far easier to reason about. (P8).
The torus rules of these agars are very annoying to parse properly...
Edit: Since the background pattern is the barberpole agar, one could use
B3/S23:Tx:y±x Depending on the pattern's orientation.
Oscillators of this form for periods 2, 4, 6, 8, 10, 12, 14, 24, 28, 30, 62, 124, 126, 1022 have been found via brute force search.
The question now is if there exist such r18 oscillators of all even periods, and if so how to construct them.
I'm in for the search. Will report new periods when I find one.
(Edit: Running a single dot in a torus of length 2^n+2^k stabilizes into a
period 2^n-2^k oscillator, if my calculations are right.
So a p16, p32, p48, p56, p60, etc... would all be possible.)
Here's an example of a p120 oscillator precursor that looks pretty beautiful.
Code: Select all
x = 136, y = 45, rule = B3/S23:T136,45-1
