Simkin’s p60 is a period-60 oscillator from 2015, formed from two B60 conduits.
Keeping the loop running
The two conduits pass Herschels around a closed loop. Their reactions also produce gliders. At this period, those gliders would hit a subsequent Herschel before escaping safely.
Two eater-5 variants remove them early enough to keep the oscillator running. LifeWiki’s illustrated form has 70 cells.
Related to the glider gun
The Simkin glider gun uses the same conduit interaction, with a different timing and arrangement that permits glider output. This oscillator instead suppresses the interfering gliders.
Later reductions and related constructions belong to their respective researchers. LifeWiki credits iNoMed’s 2023 mazing-based reduction and describes a later period-40 variant by Entity Valkyrie using a hassler found by Mitchell Riley.
The source article supplies the oscillator pattern and the detailed component history.
