The p49 bouncer loop 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. On January 24, 2003, Karel Suhajda found a slightly smaller p7 pipsquirter, giving a 400-cell variant of the oscillator. Suhajda's variant was the smallest known period-49 oscillator until the discovery of Snark-based adjustable glider loops in 2013.
