Very nice! Thanks guys. (Unfortunately, whenever new converts like this show up, it takes me a long time to update the database, because they can have repercussions on many syntheses, sometimes even hundreds.)

What is the program you used to verify this orphan, and others like it? I'm interested in knowing.

By the way, I think either of these two threads is more suitable for posting things about Gardens of Eden or orphans:

Hello again, FractalFusion!

What is the program you used to verify this orphan, and others like it? I'm interested in knowing.

it's some custom made bruteforcer with backtracking and some optimizations, a bit too dirty to publish it as is.
you just gave me an idea to re-verify it with SAT generator i've used before that.

By the way, I think either of these two threads is more suitable for posting things about Gardens of Eden or orphans

yep, seen it, thought it's too old.
i've also found GoE with 45 on-cells in 11x11 box, same as current record but D8, will post it soon.

Unfortunately the gliders couldn't have gotten to that point without interacting first. Try moving them both back 8 generations (2 cells) to see for yourself.

The best R synthesis is 3 gliders, though in many cases only 2 need to be synchronized.
