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:

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.

Slow salvo synthesis for still life in the small MWSS-to-G. What's silly but useless about it is that the catalyst does a catalysis immediately after forming.

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.
