37P4H1V1.2 is one of the two known period-4 c/4 diagonal spaceships with 37 cells. Excluding pseudo-objects, it is the smallest known spaceship with diagonal mirror symmetry in terms of both bounding box and minimum population.
On July 20, 2025, Goldtiger997 found a final synthesis step for this spaceship, and KtT used it to complete a 49-glider synthesis.[1][2]
