Actually, it is. It's the p16 from 69P48 (at least known since 2002, was it discovered earlier?), only with a very different stator in tetramer form

siffrin normal found a p9 T-nose tetramer on February 11th, which can be reduced to the following monomer:

The reaction is an input glider hitting three blocks arranged in the corners of a rectangle, resulting in an output glider and the same arrangement of three blocks (but flipped). The oscillator performs the reaction twice during each period.

Moving pairs of the snarks further away can increase the period by any multiple of 8. The period can be reduced to 628 if the eaters of some pairs of snarks are welded together.

Oscillators using the reaction were possible before, but using snarks makes it simpler and smaller. (It is fortunate that the input and output gliders of the reaction have the same color, otherwise larger glider reflectors would have been needed.)

Can someone please tell me who found the reaction and when? Thanks.

I found it by putting hotcrystal0's partial into JLS, identifying the p5 cells, and clearing them (leaving the p10 cells intact). Using p5 cells I set up a rotor-width-35 search and looked for partials up to length 35. To reduce the size of the search space and give better partials, I used the JLS setting "Search->Options...->Constraints->No more than N active cells per layer" and set this value to 10 with "excluding manually set cells" checked (this means no more than 10 rotor cells per "layer"). I also unchecked "define layers through sorting" so I could chose "Rows" as my layer type. Important note: LLS does not apply the "No more than N active cells per layer" to regions with the 4th or 5th subperiod (this allows more complex search setups, but it can be confusing if you don't know about it). For that reason, I had to set up my subperiod-5 cells by using the 3rd subperiod and setting that to period 5 under "Edit->Properties". Since I was just looking for partial results to start with, I used the LLS `-j` option to save the solution back to .jdf (JLS state file) format.

Running the above search, I found a partial result in which the rotor seemed to thin out nicely in places. I opened this with JLS and ran a thin-rotor-width search with JLS to see if any nice extensions could easily be found, and it found promising enough extensions that I just manipulated the search area a bit to quickly get the above result in JLS, without needing to go back to LLS. Finally, I optimized the stator with my stator optimizer script, and manually edited it to be symmetric.

I'm sure much smaller solutions exist.
