The p49 glider shuttle is a period-49 oscillator discovered in its original form by Noam Elkies on August 1, 1999, and was the first period 49 oscillator to be found. It consists of four p7 bouncers reflecting four gliders around a period 49 track. In the infobox a slightly smaller pipsquirter 2, found by Karel Suhajda on January 24, 2003, is used.
In terms of its 400 cells, it was the smallest known period 49 oscillator until the discovery of Snark-based adjustable glider loops in 2013. Currently the p49 R-pentomino hassler with 158 cells is the smallest p49 oscillator.
