# Talk:30P4H2V0.4

Heh, "just a few" seems like a slight understatement of the number of gliders needed. I *think* that the pattern from this forum message is the current best partial result. Am I missing some further development from another thread?

- I changed the wording on the page to say "...that cannot [currently] be constructed by gliders", rather than "...that can". That's what was meant, right? Apple Bottom (talk) 11:21, 13 October 2016 (UTC)

- Well, no. 99% or more of known spaceships can't be constructed by gliders (by any known method). This one has been known to be constructible for a year, but we didn't know how many gliders it would take, because nobody had bothered to construct the incredible mess of still lifes that Kazyan invented as a seed for the spaceship. So there was no number-of-gliders and no _synth file available -- until this morning. 111 gliders is the upper bound:
