Yes. Peter Raynham found that over 40 years ago, and it may have already been known then. You can pretty much assume that all 1-glider collisions into small objects have been tried long ago, and that also includes symmetric arrangements of multiple reflected or rotated copies of one glider around small objects. This is not to say that you shouldn't try them - there is much to be learned, even in territory that has been previously explored. I'm just saying that if you make discoveries in such areas, they have likely been made before, many times, by many people, so posting them won't be useful. You can find many copies of this reflector in use on the wiki, or various pattern collections.

Thank you both for informing me of this. (I saw muzik's reply earlier, but I was unsure as to how I should formulate a reply.)

This was posted a few years ago. However, I noticed something interesting: the queen bee is shifted one cell to the right after 28 generations. Could this mean that a (relatively) tiny c/28 spaceship is just waiting to be discovered, even if the stabilization is large?

Three siamese loaves in 7 gliders:

I don't know how many gliders this previously took, but I am approximately 99% sure this is an improvement if this is unknown, which it might not be, considering its simplicity.

EDIT: LWSS-on-LWSS pseudo-spaceship in 6 gliders:

Is this known?

Didn't you just post a mirror-image of this 5 days ago? (I noted the date, but not which forum it was on). The mechanism was indeed known, but it used to take 5 gliders to make the HF+3/4TL combo, for a total of 7. You doing it from only 4 reduces this.

Surely the completion of the 17-bit SL Syntheses thread means that there was a known synthesis?
The latest version of the 5S Project contains over 226,000 spaceships. There is also a GitHub mirror of the collection. Tabulated pages up to period 160 (out of date) are available on the LifeWiki.

The completion of the 15...18-bit still-lifes synthesis projects only provided explicit syntheses for those still-lifes that had not previously been determined to be trivially buildable from smaller/simpler ones (for example, for the 17-bit ones, there are 3286 still-lifes, 198 of which are non-trivial in this sense). The combination of the many trivial implicit syntheses, plus the remaining manual explicit syntheses, provided exhaustive proofs that all still-lifes of these sizes have syntheses.

In this case, each of the two teardrops could be made from a carrier for 4 gliders, so it could be made from 15.918 (my notes say this costs 10, but I haven't cross-checked it with Bob Shemyakin's latest lists), for a total of 18.

A really odd component:

Code: Select all

x = 22, y = 22, rule = B3/S23
9bo$9b3o$12bo$11b2o6$o$b2o$2o6bobo2b2o4b2o$9b2ob2o5bobo$9bo4bo4bo5$5b
2o$6b2o6bo$5bo7b2o$13bobo!
The middle object at T=16 was brute-forced, so someone can probably find a more elegant/cheap version.

EDIT: Popseq found this but there's no clearance (cri) (sayad):

Code: Select all

x = 25, y = 20, rule = B3/S23
16bo$15b2o$15bobo$11b3o$13bo$9bo2bo5b2o$2b2o14bobo$bobo3bo2bo7bo$bo$2o

EDIT2: 9G Component to extend a vessel by 5 that is probably overexpensive:

19bo$17b2o$18b2o2$16bo$12bob2o$10bobo2b2o$11b2o3$6bo$7bo$5b3o$15bo$5bo

It is definitely useful! This is somewhat edgy (on the "spoon" end), so it allows synthesis of the two remaining unknown jam-on-jam pseudo-oscillators (EDIT: from 12 gliders. Furthermore, these are cheaper than any the 6 conventional ones that induct stators, which take 14-15 gliders each). Unfortunately, it forms irregularly (i.e. its first two cycles are period 3 and 4 before it settles down), so while it can be combined with itself, it will be less likely to be able to be combined with others. I don't know of any caterer syntheses that are edgy on the same edge.
The caterer synthesis that involves two gliders into a constellation is edgy on the opposite edge, and it can be used to form one of the caterer-on-caterer pseudo-oscillators, but it also forms irregularly, so the rotationally-symmetric version doesn't work. (The 9 remaining unsolved basic non-trivial P3 pseudo-oscillators and the one similar P4 up to 26 bits are also shown below).

I studied a bit the collision between of a glider and a blinker. In most of all constellations all cells disappear.
However, similarly as for glider-glider collisions other outputs are possible. This is:
- block
- blinker
- traffic light
- ship
- loaf
- pond
such as three Methuselah:
- #1 a house (which is essentially the Methuselah from the Pi-heptomino, it produces no gliders)
- #2 a 8J (see http://codercontest.com/mniemiec/meth.htm#meth-8 , it produces 2 gliders)
and another Methuselah, that is not in the actual data base (http://codercontest.com/mniemiec/lifesrch.htm), I call a glider-blinker mess:

The #3 Methuselah has a lifespan of 2604 generations (just above the glider-mango mess) with a final (constant) population of 279.
It produces:
blinker: 30 (including 3 traffic lights)
blocks: 27
beehive: 6
glider:5
boat: 4

So, it produces 5 new gliders (that fly in three different directions) which is more than any collision of two gliders. This might be used to build fancy chains.

I know that the Methuselah itself is not that impressive, but as it results from a glider collusion with one of the most present object it is worth considering it. By the way, unfortunately a collision between a block and a glider never produces any glider.

The glider-blinker mess:

Cute! Normally, a traffic light takes 2, a blinker takes 2, and a bakery takes 3. This adds up to 9. How are you doing it in 6-7? Do you have a way of making two of those components more cheaply?

Is there a 3G synthesis of the two-pi spark (piehard?) that can make this synthesis work for 10G?
(Is the 13G synthesis listed in the collection the best known?)

Unfortunately, this synthesis doesn't work as shown, because one glider from each pi interacts with one glider from each B heptomino early.

13 is the best that I was able to come up with, and I doubt anyone has a better one, as most people don't tend to be interested in pseudo-objects most of the time, unless they're necessary ingredients in a larger synthesis. It's quite possible that the "pi hard" comes up from 3 gliders somewhere, but I don't have any instances of it doing so.
