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: DisplayPort actually is neat, but USB-C...
gollark: Lack of knowledge of anything about safety?
gollark: It's weird how no other consumer standards are optical.
gollark: "Optical audio" is TOSLINK, which is actually digital.
gollark: I find it kind of triangular myself.
