p73 lumps of muck hassler is a period-73 oscillator found by Luke Kiernan on October 30, 2022. In terms of its minimum population of 68 cells, it is the smallest known oscillator of this period; it and a related oscillator are also the only known oscillators of this period that do not rely on glider loops or Herschel track technology. It consists of two lumps of muck being hassled by a pair of bookend catalysts, a pair of tubs, and a pair of fishhooks.

The finding of this p73 completed one of David Raucci's partials, as shown below. The object being hassled is a medium-lifespan traffic light predecessor.
