Period-89 oscillator engines

A p89 pi-heptomino hassler partial was found by David Raucci on May 25, 2021:

Dave Greene completed the partial into an oscillator with bounding box 239 × 183 and minimum population 2116, using six glider streams to support the reaction.

Matthias Merzenich reduced the number of supporting glider streams to four, by catalyzing an interchange synthesis:

Sphenocorona found a way to support the oscillator with only two glider streams, using a suitable Herschel-to-domino converter. May13 completed this solution to a 768-cell oscillator with bounding box 219 × 74, and Entity Valkyrie 2 reduced it to a 902-cell oscillator with bounding box 143 × 86:
