It's in jslife with a different stator — osc/o0008.lif, third row, first from the left. It can, however, be reduced:

The 11 cycle idle time between the two beehive flips can be split in six different ways, giving populations 123 (0+11), 124 (1+10), 122 (2+9 as shown), 124 (3+8), 126 (4+7), and 124 (5+6). Combined with cis and trans versions, this gives 12 basic isomers. It also looks like it ought to be possible to synthesize. Synthesizing one half of the stator is easy. Synthesizing the second will be a bit more of a challenge, and I suspect the biggest problem will be in inserting the two B heptominos into the assembled stator. Both of these should be slightly easier for the trans versions.

WOW! As others have said, we are curious to know how you found it.
Stabilization of A for awesome's partial/troll.
Gratula to the discoverers! As it was mentioned before, this is likely to be a POTY! A famous quote from and old Predator-saga movie: "Okay, who's next?" - someone quickly updated this table with fresh results and created the relevant dedicated entry: So periods to be find: p19, p38, p41, and a nontrivial example for p34.

I also have a user page for this oscillaotor listing 12 variants and a pseudo-period monomer.
The ENEERG-y of the EVAD is watching.
The 70th NAI-ve guy is watching.

There is a nice potential p49 in the osc-supported section of jslife consisting of 4 interacting traffic lights. According to JLS there is no p7 that can provide the necessary dot spark, but there is another possibility that looks like it has some promise:

Code: Select all

x = 39, y = 27, rule = B3/S23

Can anyone find a p7 oscillator to complete this p49? If so, I think it will be the first p49 that is not a glider loop.

Looking some more at the osc-supported section of jslife, I noticed that one of the p72 reactions could be supported by Elkies' p36:

18b2o$18bo6b2o$20bo4bobo$20bo6bo$27b2o!
At first I thought it didn't work, because a domino spark from the p36 interacts with the p72 engine where it wasn't supposed to. However, it turns out that this extra interaction actually saves the pattern. Without it, the p72 engine would destroy the p36 oscillators.

I've been trying to solve some old problems with new technology. Here is a stabilization of a p13 wick from jslife using one of the new p13 oscillators:

This wick is very sparky, so I was hoping it might be useful for something else, but the sparks are very similar to those produced by the p13s that stabilize it. Does anyone see a use?
