66P13 is a period-13 oscillator and sparker that was found by Bullet51 on November 12, 2019. A monomerized version and a stator reduction were found by praosylen and Matthias Merzenich respectively shortly after, producing the version shown in the infobox. Over the next day, various hassling oscillators were posted using variants of 66P13, including a bi-block hassler, a block-and-pond hassler, a bumper loop, and a ship hassler.
