A simple blinker hassler, period 80, but unfortunately not the smallest one:

Code: Select all

x = 43, y = 17, rule = b3/s23
13b2o13b2o$13b2o13b2o2$13bo15bo$14bo13bo$10b2o3bo11bo3b2o$15bo11bo$13b

b2o37b2o$b2o37b2o!

It also works with p40,e.g.:

Code: Select all

x = 43, y = 17, rule = b3/s23
14b2o13b2o$14b2o13b2o3$38bo$37bobo$2b2o11b3o13b2o3bo$b2obo8b2o2bo4b3o

32bobo$33bo3$2b2o37b2o$2b2o37b2o!

The spark might be useful.

You can almost get a second glider out this way, but patching up the internal debris has to get creative:

Code: Select all

Awesome! Trombone slide guns without a syringe!

Unrelated, here's another p36 honey farm hassler. It's likely that there's a more compact version and/or one with only still lifes to support it:

here's another p36 honey farm hassler.

Cool! I've seen that big still life before, but I don't remember seeing it hassle a honeyfarm in that way. I'm guessing this was also discovered by hand. If by-hand searches can be so lucrative, I have high hopes for further automated searches.

I noticed that the blocker in the new p40 honeyfarm hassler could be replaced by a figure eight:

Code: Select all

x = 37, y = 29, rule = B3/S23

Also, a new p16 oscillator was found by the mysterious "carybe" on Oct 22, 2018 (mentioned here):

Code: Select all

x = 20, y = 20, rule = B3/S23
10b2o3b2o$10b2o3b2o$6bo$2o3b2o$2o2bo10bo$5bo3b2o2b2obo$5bo3bo6b2o2$2o$

2o3b2o$13bo$3b2o3b2o$3b2o3b2o!

It has some fairly strong sparks, but I don't know of any particular uses for it.

Nice oscillator!
Sadly, this mazing doesn't quite pass muster:

3o3b2o$6bo5bo3b2o3bo2b2o$13b3o2b2obo$15bobo2bo$16bobo$17bo!

(Notice it's not actually broken at gen 10)
Messing around with a unix didn't produce any results wither, and I'm not sure what other smaller options exist.
EDIT: As for still life supports, it'd definitely require a custom catalyst; the standard interactions either get interfered with or interfere with something else.

[2718281828]

The new p64, is somehow related to the thunderbird:

Code: Select all

x = 44, y = 27, rule = B3/S23

#C [[ STOP 56 ]]

This might be taken into account for finding a name.
This pattern by itself evolves as follows:

Code: Select all

x = 9, y = 5, rule = B3/S23

After searching for a different ending, I managed to shave off...one whole row:

Oddly enough, just looking at that new one and drawing in an eater by hand shaves off a lot more rows, though of course the eater intrudes into two new columns at the very bottom so it's not exactly a solution to the original problem any more.

Still I don't think the eater is going to get in the way of most things that a T-nose might get used for:

Code: Select all

x = 11, y = 38, rule = B3/S23

$o7b3o$10bo!

The eater-compatible linkage wasn't there in the original version.

Any hope of bending the p5 90 degrees near the top, and preserving that useful high-clearance side of the T-nose by extending the search west instead of south? Or is this a problem that was already solved long ago? I haven't looked through jslife yet to see what's already available.

N.B ofind is a BFS search so it will print out the shortest possible oscillator. However, I've seen it spitting out suboptimal solutions, so I guess there's a bug in there.

Edit: ofind emits this:

Code: Select all

x = 9, y = 80, rule = B3/S23

So it probably checks if the row can be stabilized with p1 parts to shortcut early. Which means EE's solution is likely to be optimal.

It looks like a p13 spark won't work, because after 13 generations there is too much debris in the spark location. Unfortunately, we don't really have any p26 sparkers. For now it will make a good addition to the osc-supported folder of jslife:

So it might be possible to find a 'single engine gun'. Unfortunately it does not work with the p4 sparkers (jslife) we have for a p92 gun.

It only works if the spark is supplied at a multiple of p23 (otherwise it interferes with the shuttle in the wrong phase). The first good period for which we have a non-p46-based oscillator is Gabriel's p138, and this is exactly the mechanism in the p138 gun in Peter and Dieter's glider gun collection:

but that's not quite compact ^^

A pentadecathlon can provide the magic spark to get the second glider out the other way, so there's this sequence of p30(2n+1) guns starting at p150. These won't set any records, but are edge-shooters and the longer ones are shaped roughly like thin diagonal rods, so they might be more friendly to work with when building large shotguns.
