Odd keys is a period-3 oscillator found by Dean Hickerson in August 1989. It is one half of bent keys combined with one half of short keys, and it can be extended horizontally as in the original form of Jason's p33.

Synthesis

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