The cis form is definitely an improvement! I previously had a brute-force 30-glider synthesis of it from 2016-01-17 (I don't think I posted it, as it didn't include anything new). I reported the exact same synthesis of the trans form on 2016-01-03 (see Soup Search Results p.33).

That can be done with 20, saving one glider in the initial constellation and one in the cleanup. Unfortunately, I don't know of ways to make two adjacent beehives or two nearby beehives from 3 gliders each (although I am sure there are ways to do so). Extrementhusiast also found a 15-glider solution on 2015-07-04 (see end of page 14):

I couldn't find the component to add an R-bee-siamese-tub, so I made my own inefficient (15 gliders) one. The following synthesis can probably be easily improved through that.

Here is the full synthesis in 49 gliders:

@Kazyan, what is the component to add an R-bee-siamese-tub you were referring to?

Great work, guys! This was the last loose end from Dave Buckingham's massive synthesis project. In the 1990s, he had synthesized all stable objects up to 14 bits, and all still-lifes up to 14 bits for no more than 1 glider/bit. Due to one bookkeeping error, one still-life ws actually 15 (which I believe was reduced last year), and this one P2 was not in his synthesis list. (He said he had a synthesis on a notebook in his attic somewhere, but he never found it).
Goldtiger997 wrote:I couldn't find the component to add an R-bee-siamese-tub, so I made my own inefficient (15 gliders) one.

It seems like yours adds bun-siamese-tub in 13, and bun-siamese-boat in 15. The current converter I have adds bun-siamese-tub in 15, so yours is better.
You can save 1 glider by using a different diagonal-bit-spark:
(-4 for unnecessary eater, +1 for pond to ship, +2 for spark):

This fix also reduces this one to 40.

You had posted this one before; I had added it to my 3x3 block synthesis no later than 2016-12-13.

Nice! This may also solve some of the other difficult cis-shillelagh syntheses, or at least provide alternate paths to some of them. (Of 10 syntheses I have that lack such alternate paths, this solves 6 of them).
The mechanism to add a cis-shillelagh starting from an inducting mouth used to take 28 gliders (27 if boat-bit can be used), and this reduces it to 19 in most cases, so even those syntheses where an alternate path exists, this usually improves it.

I just noticed that not only are there the 3 basic trivial stator variants of 29P9.1 (with table, trans- and cis- carriers), but there are also three others, with a different bottom right corner. Extrementhusiast created a synthesis for the first one on 2016-08-06, and #3 and #2 can be made trivially from this. #6 and #5 could similarly be made trivially from #4. A synthesis for #4 could probably be done by altering the synthesis of #1, but it's a bit beyond my expertise.

Re: Synthesising Oscillators

Is there any reason why chris_c's glider_synth script could not be extended to oscillators as well. We have syntheses for all oscillators up to 14-bits now. Here is what I think are the cheapest for all oscillators up to 14 bits:
oscill3-14.7z
(4.16 KiB) Downloaded 37 times

There are probably heaps of mistakes.

P.S. Has anyone made any progress on synthesising the last 15-bit oscillator, muttering moat 1:

x = 7, y = 7, rule = B3/S23

There are probably heaps of mistakes.

I didn't see any errors, although there are a few minor stylistic things:
- in "9G fox", the final step takes a while before the gliders interact. I usually have them placed in such a way so that the "before" and "after" images are in phase (so when run simultaneously, there are two synchronized objects), the "after" image is the specific phase I want, and it is impossible to run the "before" image by a full cycle (in this case, 2 generations) without the gliders interacting.
- in "30G 14 bit P2 #4" - the last step's "before" image shares a column with the previous step's "after" image. These should probably have more separation. Also, there is an "after" image for all steps except the first.

You are missing one improved synthesis: Phoenix from 6 gliders, by Extrementhusiast 2015-03-01:
x = 33, y = 14, rule = B3/S23

12boo$bbo3bo24bo$bo25bobo$29bo$10boo$9bobo$11bo!


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?

There are now syntheses for most oscillators up to 21 bits, except 3 20-bit P3s, and many P2s (because P2s are simple enough that many viable ones exist, yet are complicated enough that they are difficult to synthesize. Larger oscillators are usually easier because they are so much rarer).

Sadly, not that I am aware of. (Once solved, this will also solve the last two unsolved 19-bit P2 pseudo-oscillators).
