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 James Pascua. On March 2, 2021, cvojan found an alternative stabilization which cut the sparker's population nearly in half.

This oscillator was originally discovered as a dimer, with the stator reduced to 1308P7 (shown here). The Wiki page used a slightly larger form of 1320P7.

However, none of the smaller domino sparkers could support it, so this trimer form was just a curiosity, for now. In March, cjovan found a way to massively reduce the gutter stabilization, to create 754P7.
