I'm usually pretty quiet about what I'm working on, but I've been working on trying to get RCT down to 14, if it's possible, by synthesizing the southwestern-most pair of switch engines in 6 gliders instead, using a method like this:
x = 1724, y = 1729, rule = B3/S23

4c/(118+640n) in B35e/S2-i36c:

I apgsearched this rule in C1 quite a bit, it yielded this p30 gun made out of two wings (EDIT: almost certainly appeared in D8_1 first):
x = 8, y = 8, rule = B35e/S2-i36c

I feel like such a pattern exists, and could possibly be done via some weird UC encoding that somehow ends up constructing its recipe but with glider predecessors like this:
x = 12, y = 5, rule = B3/S23

New rule, I had discovered a rule called Nucleus (B3aijkr4eknqz5-cein7c8/S2-i3aceiq4ejqrt5cijq6c7c) around early 2021, and posted a few things in it on Discord. I never really posted it here for some reason. Unfortunately it's not a very active rule and so there wasn't much I could find.

hello 2.5 year old thread

I've been playing around with a rule I've named in my files SharkLike , after Rhombic's 2017 rule SharkLife .

It has a lot of common linear growth patterns, which I've listed in descending order of frequency:
x = 33, y = 116, rule = B34k/S2-a3-n4aeny5y

You may have been banned. If you PM me (or post) your Discord handle I can look it up and see.

I feel like that's not the case though, because if someone's banned it typically says that the invite was expired, not throw an error.

I made a rule much more like Coexistence:

Is this known? Is this a Methuselah? I'm not sure because my computer can't run a simulation for so long.

It stabilizes back to linear growth at generation 29071 after burrowing through a traffic light. It's not considered a methuselah because it ends with linear growth (which I think is kind ...

In HighLife, replicator collisions can often turn messy fast. Here's a 16-cell pattern, derived from the 39th zz_QUADRATIC sample soup on Catagolue (as that was the last one at the time of writing this question):

Two properly-timed herschels make a switch engine relatively cleanly. The eater gets rid of one blinker, but the other looks impossible without using snarks:

Lovely pattern that turns into a dodecomino in generation 1, suddenly becomes symmetric in generation 10, and stabilizes at generation 126 to a clean set of 20 blinkers:

Can periodic stabilizations (e.g. p3) exist? I can't check right now because I'm away from my computer, but this can be searched via JLS or LLS I think.

That's definitely on your end, it looks fine for me.

The "block and glider" methuselah can be "extended" one cell and still converge the same sequence. However, if you extend it a similar way 13 times from the original, it actually ends up evolving into a block and a glider in a different way:
x = 63, y = 17, rule = B3/S23
