Double X is a period-46 oscillator based on the twin bees shuttle that was found by Robert Wainwright[1] and exhibits two interesting reactions. First, it shows how a twin bees shuttle can be used to convert a glider into a lightweight spaceship. Second, it shows how a head-on collision between two lightweight spaceships can produce two gliders.
A 91-glider synthesis of this oscillator was found by Jeremy Tan on July 11, 2019.[2]
