Merzenich's p64 in 14G: (the 3G for the active object was found by, you guessed it, synthesise-patt)

Code: Select all

x = 43, y = 43, rule = B3/S23

Reduced to 10G using popseq, synthesise-patt and some trickery:

Code: Select all

x = 37, y = 33, rule = B3/S23

Glad to see my script is being this useful!

Where can you get copies of this script?

Code: Select all

x = 5, y = 9, rule = B3-jqr/S01c2-in3

Here: https://github.com/dvgrn/b3s23life/tree ... esise-patt (it's a Python script for Golly)

I've been looking through Catagolue to see if it has any syntheses for oscillators in my collection that are >= 1 glider/bit. It has removed most of the P4s from my list (except for the few I haven't had time to examine yet). I did notice that it's using a sub-optimal mold converter; the one below is cheaper.

Code: Select all

x = 76, y = 21, rule = B3/S23

48bo17bo$6bo44boo3boo$50bobobbobo$7boo43bo$7bobo$7bo8$20bo$19boo$19bob
o!
One 21-bit cuphook had a 77-glider synthesis, but Catagolue doesn't list it. Fortunately, it has a soup that reduces this to 11. It might be possible to reduce this by one or two by using a 3-glider pond+bit spark above, and/or a less obtrusive 3-glider wing to allow a 2-glider bit-spark on the left.

Code: Select all

x = 88, y = 33, rule = B3/S23

Great! What is truly absurd is that my wing collection has 7 syntheses, and this (plus the complement with the glider approaching from the other direction) are two of them, yet I didn't think to use them!

Jason's p22 reduced from 12G to 11G:

Great! From the list of collisions you posted, I found 9 that could safely place one copy of the object, one of which can be used to place both, giving 10 gliders:

EDIT: I had the 11-glider synthesis in my records; it was posted by 2718281828 on 2017-12-06.
EDIT 2: This also improves the 50p44 with mold and 50p88 with figure-8, but not the 48p66 with caterer or 51p110 with pseudo-barberpole.

In addition to what Ian07 said, you could also spend a very long time synthesizing things in OCA for good practice. (That's what I've been doing). Basically, what you do is look at Catagolue soups and then see how the soup made the object. If it was made with objects that you have a synth for, you might have a synth.

If you've gotten Python scripts in Golly to work, there's an easy way to check this on Catagolue yourself with the second script from this post. Just select a pattern, run the script, and it'll send you to Catagolue, where you should see the current best synthesis if there is one. (though a few syntheses still need to be ported over)

If you're like how I was for a while and could only run Lua scripts, unfortunately I don't know how to help you there unless there happens to be an equivalent Lua script somewhere on the forums that I haven't seen.

If there's a way to covert a [8.5] to [10.4], then it should be possible to convert the [14P2.18] into [16P2.79].
Similarly, a conversion in the other direction could reduce [18.475] .

Unfortunately, that is an exercise for the student, as neither conversion seems to be available, at least in my files.

I'm pretty sure I have the reverse transformation somewhere in my files, but I'd have to find it first! (However, I'm sure I could whip something up anyways.)

EDIT: Oh yeah, the reverse is much cheaper:

Code: Select all

x = 47, y = 19, rule = B3/S23

That's what I was thinking of. Thanks. Didn't occur to me to look a little deeper and see if there was anything that required two steps, where the first step adds to what is to be removed.

The second step I have is slightly different. Only advantage is that this one is quicker.

Code: Select all

x=10, y=18

The former has the advantage that no gliders come from the northwest. The only time one needs a construction like this is when the hook is already attached to something else, and in that case, it's often safer when incoming gliders are less obtrusive, to be less likely to interefere with whatever that something else is, as duration of dying sparks is rarely an important concern.

Found by Alex Greason, this reduces an intermediate step of Rich's p16 by one glider:

Code: Select all

x = 60, y = 19, rule = B3/S23

The core reaction consists of pi+bun, but there doesn't seem to be a way to put two 2G collisions together. Any other ways to reduce this to 4G?

This only just works:

Code: Select all

x = 19, y = 24, rule = B3/S23
