P29 pentadecathlon hassler is a period-29 oscillator where a pentadecathlon is hassled by two copies of a p29 pre-pulsar shuttle variant. It was discovered by Bill Gosper.[1]

The hassled pentadecathlon emits a domino spark, enabling the construction of p58 toadsucker. In addition, Matthias Merzenich discovered a color-changing glider reflector at minimum repeat time 58 ticks based on this in 2012.[2]

GUYTU6J found a 78-glider synthesis of this oscillator on April 18, 2020.[3]
