754P7 is a very large period-7 oscillator and high-clearance heavyweight sparker. It was originally found in a dual form by wwei23 on January 17, 2021, through an observation of a blank row in JLS leading to the stabilization of the sparker across a gutter. Its stator was slightly reduced to a 1308-cell form by BlinkerSpawn and JP21. On March 2, 2021, cvojan found an alternative stabilization which cut the sparker's population nearly in half.
