Strictly volatile p89 in Applelife:

Code: Select all

x = 14, y = 17, rule = B34a5i/S23-a68

Code: Select all

#C [[ ZOOM 8 TRACK -3/87 -1/87 ]]
x = 4, y = 5, rule = B35ay/S2-i3-e4ey5j

Almost definitely known, but the bun is an interesting loaf puffer

Code: Select all

I'm not certain that the minimum width for a c/3 in AppleLife is 23, but all other widths below have no results. This is what RustLife pumped out for me, it seems to be quite the large spaceship for its speed.

Code: Select all

x = 19, y = 23, rule = B34a5i/S23-a68
