The p49 bouncer loop 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 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.
