I originally discovered this as a partial/troll (it looked like this except replacing the symmetric induction coil thing with a block), then literally within 2 minutes of coming back to it, I found a completion that only adds 2 extra cells to the rotor.

I couldn't find the rotor in jslife, osc_supplement, or the oscillator stamp collection, so I'm not sure if this is new, since it could be in some other place.

It's known (found by Bullet 51 in 2015 using dr), but the way you found it seems to be quite interesting. How was the partial/troll found?

To check if this oscillator was known, I used the process given here.

It's known (found by Bullet 51 in 2015 using dr), but the way you found it seems to be quite interesting. How was the partial/troll found?

The furthest back I can remember that is related to this was this p8 partial, where 2 cells need to be suppressed twice:

Code: Select all

x = 13, y = 14, rule = LifeInvestigator
4.A$3.A.A$3.A.A$.2A2.2A2.2E2A$A2.2A5.A.A$.2A2.2A3.A$3.A2.A.A.A$3.2A.A

(I'm not sure if this has been completed or not, so let me know if it has.)
I noticed that mirroring it onto itself vertically wouldn't work, so I tried to mirror it onto itself diagonally to see if it had any potential:

Code: Select all

x = 21, y = 21, rule = B3/S23

4b2o!

I was expecting for it to break down immediately, but it turned out to actually have a completely different evolution.
I quickly noticed that it was ALMOST a p11, but only one cell needed to be surpressed.
So I posted it on Discord as a troll/partial, and decided to come back to it later.
It turns out, the partial wasn't as complicated as I thought, and only needed a tiny change: changing the block to this symmetric induction coil.

I think the "Tanner's p45" name refers to the fact that Tanner Jacobi found the underlying engine (Tanner's p46) & the name stems from the similarities it shares with Tanner's p46. The "previous one" probably refers to some previous completion of the p45 variant which relied on a glider gun.

EDIT:

It would be nice to have the discoverer of the p45 clarified, because otherwise the suggested name is likely to be interpreted as attributing the discovery, and people might end up talking about "the oscillator that is not Tanner’s".

Comparing the p46 and the p45, the longer pi-to-pi conversion is preserved (as a variant), but the shorter conversion is changed to a different one. Here is a comparison between the two oscillator engines:

Code: Select all

In this case, I really don't think it matters that much. Most phases do match (To count 37 out of 45/46, & all but one of the steps involved with PT8P are altered), & changes to the evolution of the pattern were inevitable (if not, then the oscillator would end up just being Tanner's p46 all over again). Overall, the p45 oscillator exhibits extremely similar behavior & capabilities to Tanner's p46

It would be nice to have the discoverer of the p45 clarified...

I discovered it. The mechanism is by Tanner Jacobi and the original p45 rephasing is by FWKnightship. I don't think any further clarification is necessary.
