Pentoad 2 is a period5 oscillator that is shown as the second pattern in the sixth row of Jason Summers' main period 5 collection. It is extensible. The central part is the same as in pentoad.
This oscillator first appeared seminaturally in September 2016.^{[1]}
Synthesis
A 16glider synthesis was found by Jeremy Tan on March 19, 2019,^{[2]} which was later improved to 12 gliders by Goldtiger997.^{[3]}
