I was not aware of that one, but the standard 3-glider method works just as well. Both insert at the minimum possible separation. Here are the other LWSS, MWSS, and HWSS syntheses I know that can insert spaceships at minimum separation (14, 16, and 18 generations respectively). Two had to be slightly tweaked:gmc_nxtman wrote:Is this from-the-front LWSS inserter known? ...

I don't believe so, but the synthesis wiki hasn't been updated in quite some time (I think waiting for a robust way to handle new records semi-automatically) and the Methuselah section in particular hasn't really had much attention paid to it; most synthesis attempts are focused on still-lifes and oscillators.2718281828 wrote:Are these 3-glider synthesis for Acorn, Multum in parvo and Thunderbird known?
I know of one different 3-glider synthesis for Thunderbird, found by Extrementhusiast on 2015-07-04. All the others are improvements. Very nice! I was not aware of 7468M; I will add it. I am trying to list all important methuselahs below 10 bits.

An exhaustive examination of all 3G reaction has, to the best of my knowledge, never been done. Dave Buckingham did a fairly comprehensive study of them back around the 1980s or so, but the fact that occasional new 3-glider syntheses have come up over the past few decades (e.g. pentadecathlon, bi-pond, infinite growth, and switch engine, plus the ones you posted here) show that he didn't find all of them.2718281828 wrote:I am working on the enumeration of all 3G reactions
There are a lot of people who will be interested in this. You should discuss your methods in this topic. Someone might be able to give some helpful suggestions. Personally, I'm curious how you plan to deal with the 2-glider collisions that release gliders (e.g., 2-glider mess and B-heptominoes).2718281828 wrote:I am working on the enumeration of all 3G reactions.
Hear, hear!

Luckily there are only a few collisions that do that -- a total of seven, including the three B-heptomino outputs and 2-glider mess that Sokwe mentions, plus the two kickback reactions and the TL+glider reaction. The kickback collisions are relatively easy to get a complete enumeration for, but the B-heptominoes and the others seem fairly painful.Sokwe wrote:Personally, I'm curious how you plan to deal with the 2-glider collisions that release gliders (e.g., 2-glider mess and B-heptominoes).

Thanks for checking!
