The first engine-based period-61 glider gun was discovered by Mitchell Riley on April 5, 2023. The active part of this gun consists of two symmetrically arranged honey farm sequences. With bounding box 47 × 44, it is the smallest known glider gun of this period, beating the previous signal-loop-based design with bounding box 101 × 88.
