25P3H1V0.2 is a c/3 orthogonal edge-repair spaceship that was found by David Bell in 1992. With 25 cells, it is tied with 25P3H1V0.1 as the smallest c/3 spaceship.[1] The final step for a glider synthesis of this ship was found by Martin Grant on December 15, 2017,[2] which was turned into a complete 26-glider synthesis on December 31 due to contributions by various people.[3]
