Wait, what? You've reintroduced the eater that I removed from the Fx77 (in order to use the FNG from the output Herschel to delete the blinker instead).

Re: The Hunting of the Elementary Conduits

Specifically, one can remove a fishhook, a block, and a loaf, and this allows the Fx119 to be follwed by an independent conduit. If you're following it with an independent conduit, then you can remove another eater without impacting the recovery time: x = 216, y = 184, rule = LifeHistory C$.2C$2C10...

Why are there two p2s called "beacon on something" and ":D"?
"something" was imported from an older census, and ":D" was Calcyman's idea of a joke.
I don't think it was my idea; I copied it from an anonymous comment someone made on the page.

Using messless as a proof-of-work would have the problem that people would discard a soup as soon as it has an escaping glider, and therefore miss lots of discoveries that would have been found by running those soups to completion.
