The p50 glider shuttle is a period-50 shuttle oscillator found in its original form by Dean Hickerson on March 19, 1992[1] and was the first period 50 oscillator to be discovered. Its original form used an early version of toaster and was based on a period 66 oscillator[2] discovered by Robert Wainwright in September, 1984.

The oscillator works by using two copies of eater 3 and four copies of a period-5 sparker found by Noam Elkies to shuttle two gliders back and forth. By increasing the distance between the two reflectors, oscillators of periods 50 + 40n can be created. 5blink works in place of Elkies' p5 sparker, but only for periods above the minimum period. In March, 1992 Hickerson created a related oscillator by crossing two pairs of gliders using rephasers, which allowed the construction of oscillators of periods 230 + 40n.
