The p49 glider shuttle is a period 49 oscillator discovered in its original form by Noam Elkies on August 1, 1999,[1] and was the first period 49 oscillator to be found.[2] It consists of four 90-degree glider reflectors shuttling four gliders around a period 49 track. The glider reflectors are based on pipsquirter 2 but use a slightly smaller version of the oscillator found by Karel Suhajda on January 24, 2003. Shuttling gliders in this manner is the only known way to construct period 49 oscillators. In terms of its 400 cells, it is the smallest known period 49 oscillator.
