Do you recall roughly when? I can't find any record of it, in either the syntheses I've added to my database, nor in posts from these forums that are on my "todo" list. The activation mechanism seems to look like the one you used for Pentoad 2, and this oscillator does seem to resemble Pentoad 2, but is stabilized differently.

The activation mechanism seems to look like the one you used for Pentoad 2, and this oscillator does seem to resemble Pentoad 2, but is stabilized differently.

I think that might have been it, along with the fact that I had tried working on it much earlier, but failed at the time.

Also, I have been attempting to compile a collection of components for future use. Niemiec, could you send me a list of components that your expert system uses? That would be a helpful starting point.

[quote="mniemiec"Also, I have been attempting to compile a collection of components for future use. Niemiec, could you send me a list of components that your expert system uses? That would be a helpful starting point.

There are currently close to a thousand (i.e. 947) of them. They are in special format usable by my own DOS Life program, using 7 different states, but I can see about converting them to a specialized Golly rule. Unfortunately, they only include converters from smaller to larger objects (or ones the same size, from simpler to more complex) to avoid breaking inductive proofs (i.e. currently, if the system finds that object A can be made from B, and B is known to be buildable, it is also known that B cannot possibly have been originally built from A). This seems like a worthy project for this afternon.
I also have an ad-hoc collection of close to a thousand various converter files of all sorts that are in a much less ready-for-prime-time state.

Nice! This beats the 37-glider solution by Jason Summers and Matthias Merzenich:
http://codercontest.com/mniemiec/lg/68p32-1.rle. Unfortunately, that was first posted before I started to keep date annotations, so I'm not sure when or where it first appeared.
However, my file was last edited on 2013-03-06, so it was definitely found no later than that.

The actual oscillator was found on New Year's Day 2010, so the synthesis must have come later than that!

Ah, I didn't realise it had been synthesised before. Taking inspiration from the previous method I managed to get down to 24 gliders:

EDIT: Continuing the fun with reduction of symmetric syntheses here is 48P31 in 25 gliders (EDIT2: now 24 gliders by giving the synthesis 180 degree rotational symmetry instead of reflectional symmetry). The fact that the supporting blocks could be made with one glider each was an unexpected bonus:

Six-glider snake-to-long-hook-with-tail converter with clearance moved to the other side:

I'm fairly sure it can be reduced and made one-sided.

EDIT: Well, it can be made one-sided for either the same cost or one more glider (depends on the beehive), with even better clearance:

Code: Select all

x = 25, y = 21, rule = B3/S23

Amusingly, since this converter produces another junk beehive in the right orientation and in a compatible position, it can be chained:

Very nice!

There are several ways of capping the P156 gun, some of which double the period: http://codercontest.com/mniemiec/period.htm#p312

However, there is one missing period on http://www.conwaylife.com/wiki/Category:Oscillators_with_specific_period. It has a link to P186 oscillators, of which none are listed, and I can't find any references to any anywhere else.

Is there any cornershooting dot spark inserter that can insert a spark in either of the red locations?

Code: Select all

x = 19, y = 11, rule = LifeHistory
19B$18B$.16B$4.12B$4.13B$7.10B$9.7B$9.7B$10.4B2$8.D6.D!


Where's the rest of the reaction? What's going on around the spark insertion site determines what does and doesn't work.

Sorry, the reaction is this:

Code: Select all

x = 7, y = 9, rule = LifeHistory
3.2A$2.4A2$A$2.2A.A$.A2.2A$.2A$3.2A.A$3.A.2A!


The corresponding 3-glider block inserter would normally interfere with most dot spark inserters.

[BlinkerSpawn]

Code: Select all

x = 7, y = 9, rule = LifeHistory
3.2A$2.4A2$A$2.2A.A$.A2.2A$.2A$3.2A.A$3.A.2A!


The corresponding 3-glider block inserter would normally interfere with most dot spark inserters.

Your best course of action would probably be to do this

Code: Select all

x = 10, y = 11, rule = LifeHistory
A.A4.A.A$A.A4.A.A$A.A.2A.A.A$4.2A2$A$A2.2A.A$2.A2.2A$3.A$4.3A$6.A!


followed by the appropriate converter.

One must never forget about alternate predecessors. (Also, the three-glider block inserter doesn't work here to begin with; that one only works if there is absolutely no extra overhang on the inducting surface at the start of the reaction.)

26-glider synthesis of the last remaining non-trivial 21-bit P2 pseudo-oscillator. This uses a slightly modified version of the method Extrmenthusiast used to synthesize several of the others, but which wouldn't quite work in this case. The modified method wouldn't work near a snake either, but it does work if the snake is completed later:
