Great Job!!!

It gives a synthesis for muttering moat 1 in 21 gliders:

Are there any other syntheses like these that you have forgotten to post?

I think there are now only 4 16-bit oscillators without syntheses:

Thanks, I've fixed these, and I think have followed those guidelines for the updated version posted below.

I am curious, when and where did the synthesis for "8G 14-bit P2 #1" come from? The best one I had was 12 gliders, by Extrementhusiast 2015-01-05. Also, "30G 14 bit P2 #4"? The best one I had was from 40 gliders. Where did the improved base still-life synthesis come from?

here and here.

Here are the cheapest syntheses for all oscillators up to 15 bits:

oscill3-15.7z: (7.26 KiB) Downloaded 361 times

There probably are mistakes.

Wow. Another stylish but expensive design from Kazyan's workshop --

Is there a known mechanism for building the very-times-N long barge in proximity to the boat-tie-eater thing? I'm sure it can be done somehow, but that construction stage doesn't look like it will be cheap either.

I think you could just drop in a tub with that one pond+glider collision and then grow it out to desired length, two cells at a time. But let's wait until the others prune this step a little. There are at least two places on that long^8 barge where I simply whacked a problematic part with a wrench until it moved out of the way.

Very nice! This reduces the cost from 74 to 41 gliders, and one more cleanup glider can be eliminated by backing the NW glider by 3 steps:

Hmm. I don't know of any way to turn a block on table-like inductor into a hook w/tail; all ways I know to create such an object start with a hook w/tail and adding the inductor later. Adding a siamese snake or similar while simultaneously adding a boat should be fairly easy, and then turning the boat into a table siamese hook w/tail shouldn't be too difficult; however, growing two pythons in such close proximity will be quite a challenge.

Nice! The previous synthesis of this (17.1120 aka 17#166) took 45 gliders (unless my lists are out of date). The clock-trigger can be reduced to 1 glider, and the defective paperclip can easily be made from 4 gliders, reducing this to 9. There are also several ways of making it from 3 gliders, but I don't know any offhand that work.

Anyway, the second-to-last of the p2 oscillators is an easy kill:

I thought the final p2 could also be obtained with a tweak to this one, but no dice so far.

Does this solve all of row 10, or are a lot of the base still-lifes still difficult?

EDIT: Ah, I get it. The part that made these oscillators difficult to synthesise were their stators, not their rotors. I thought it was a bit too easy to synthesise for an unsolved oscillator

Nice. The cost was previously 6, so this doesn't improve that, but the edge-shooting dynamic is much more versatile than the previous one. From the syntheses in my collection, this optimizes 5 objects and 30 pseudo-objects.

I already had that step; what is missing is the underlying still-lifes.

Final step for another p2 on the list. I don't know how you would make the two nonspartan objects in the center, but they don't look that hard:

I can see why the objects on this list are unsolved. Right now I'm focusing on objects that look like Hard Mode rather than Nightmare or Good Luck With That Buddy.
