Nice! Here's a solution to the other part found using JLS:
Thanks for the completions and optimizations!
I was running and ofind search which gave me this variant.
That's much better! I guess I got a little impatient and sought out some solution without much regard for the best solution. I would guess that the other disconnected sparkers could also be replaced by a shorter double-sparker. Here is a stator minimization of your solution:

This can be considered a p65 pre-pulsar shuttle in the same sense as the p47 pre-pulsar shuttle. Both shuttles require a central interaction to reform the pre-pulsars.

I would guess that the other disconnected sparkers could also be replaced by a shorter double-sparker.
I vaguely thought I would cut a few rows, but I was surprised to see how small it was:
Indeed, that's smaller than I expected! Here is the stator minimization:

This can be considered a p65 pre-pulsar shuttle in the same sense as the p47 pre-pulsar shuttle. Both shuttles require a central interaction to reform the pre-pulsars.
This is a new period of pre-pulsar shuttle, which means that the wiki will need to be updated. However, it behaves differently from the known pre-pulsar shuttles, since in addition to the (14,3) mechanism at center, four copies appear at generation 29 (one pair in the original position, plus one displaced outward by 6 cells).

### Re: Oscillator Discussion Thread

Since we have a 51-generation 3-cell push, and 15-generation pushes are common just like 14-generation pushes, could we also get a p66 here? The p5 sparkers obviously won't work, but we could use p6, p3, or maybe Martin Grant's p11 (which has extremely low clearance).

The (51,3) push requires the hassled pre-pulsars to interact, so they must be a specific distance apart. It seems unlikely to me that the 15-generation push can be made compatible with the required spacing. Anyone's welcome to try, of course. I've been proven wrong in the past.

I don't think this is interesting enough for the current oscillator discussion thread, given all of these wonderful constructions...
Oscillator discussion goes in the oscillator discussion thread. This thread has no threshold for what counts as "interesting". Also, the variant in the edit is quite clever. Nice work! I've moved your post to the oscillator discussion thread.

Well, there's still this:

It would be a p138 Herschel loop if there is a suitable RF48H, or a small p6 duoplet sparker:

Can you add to or improve this Elkies–Simkin reflector collection?

does not list p10, p12 and p30 entries as in User:Entity Valkyrie 2/3-block-1-tub periodic 180-degree reflector gallery. (Well, Rich's p16 works as well but does not provide better clearance than the p8 blocker version.)

I deliberately excluded those periods; the p10 is worse in population terms than the p5, the p12 worse than the p6 and the p30 worse than the p15 - if you can use the former you can use the more general latter.

Doing a p6 weld to supply both of these sparks seems more likely:
