I decided to start a separate thread for this rule, owing to the number of posts in TFYUCA about it. Here are the main posts, in chronological order:

1. Introduction. Basic ships. (danny)
2. (8, 20)c/58 puffers and rakes. (77topaz)
3. Clean version of a rake in Post 2. (Goldtiger997)
4. Guns and miscellaneous reactions. (Goldtiger997)
5. Gun period tripler. (AforAmpere)
6. Failed gun. (danny)
7. Various guns utilizing the tripler in Post 5. Stable reflector. First mention of rule name outside of discord. (Goldtiger997)
8. More stable technology. (AbhpzTa)
9. Various eaters. First mention of the name "eagle" for the 6c/14o ship. (Hdjensofjfnen)
10. Propose splitting. AND gate. Wickstretcher. (LaundryPizza03, the author of this post.)

There are also 4 minor posts not included above.

When I came across the failed gun thread, I decided to post a solution (certainly reducible):

By the way, you might want to check Catagolue. There are some potentially useful linear growth patterns, such as this p96 (9,6)c/24 rake:

Here's a (probably) faster splitter, rp 45. But it also delays the signal and puts it out of phase, it needs some delays to be part of a circuit.

The only problem is that TOGGLE has a lucridously slow repeat time.

Some of these things are probably known, but the memory cell is, well, a memory cell, and perhaps the first in savanna.
I especially like it since READ doesn’t change the state of the cell.

I hope both isomers are known:
