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, [1] 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[2] and James Pascua.[3] On March 2, 2021, cvojan found an alternative stabilization which cut the sparker's population nearly in half.[4]

This oscillator was originally discovered as a dimer, in the form of 1308P7.
