Synthesis

In January 2000 Mark Niemiec found a 21-glider synthesis of this oscillator.[1] On August 25th 2016, Goldtiger997 found a 10-glider synthesis of odd keys, which was later reduced to 9 gliders by Dave Greene.[2]

gollark: Matrix is overcomplicated and annoying, XMPP is bee and lacks features we now like, IRC is used a little but not very popular.
gollark: There aren't really any good platforms.
gollark: There is *an* actual concern it addresses, which is very large bots harvesting user data.
gollark: It does need server admins to add it, but they can't actually audit my servers.
gollark: I mean, they *do* help with privacy inasmuch as ABR could technically harvest all message data and could not be stopped.
