As everyone knows, this rule makes patterns that look like mazes. But there’s also a lot of interesting stuff such as this c/3 wickstretcher with a 2c/3 vine climbing onto it, then burning backwards:
Code: Select all
x = 37, y = 11, rule = B3/S12345

…and a lot more.

I was very surprised to see that this rule did not have a dedicated thread (that my 30-second or so search could not pick up).

Well, I can’t find much about this rule since not much people mind it. Now most people either like CGoL or INT rules more.

There are quite a
few notable things about this rule, for instance, the lack of any spaceships only promotes the growth of wickstretchers and still lives. Here are some I collected from other posts:

2c/7 wickstretcher and two 4c/9 wickstretchers

The most common wickstretcher is a c/3. Here it is:
Code: Select all
x = 14, y = 13, rule = B3/S12345

Has anyone managed to find other speeds other than c/3, 2c/7 or 4c/9? Perhaps these are the only possible ones considering it may be hard to look for other wickstretchers with a normal search program.

Well, it would be quite nice if you showed some more notable things then.
Only p2 oscillators are listed on the wiki page, so I present to you this p3:

An asymmetric rotor - possibly the first known one?
Code:
Select all
x = 9, y = 9, rule = B3/S12345

I also noticed that there is a very common sort-of-wickstretcher, moving at (2,3)c/8. It never fully stabilizes, often flips between (2,3) and (3,2), and usually breaks after 5-50 cycles, but sometimes it seems to live forever. Look at the north-west corner of this pattern:
Code:
Select all
x = 4, y = 3, rule = B3/S12345
o$o$4o!
I wonder if it can be properly stabilized.
