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] It has edge-repair capacities, and a Fly can be attached to it.
Occurrence

At 25 cells, it is one of the three smallest spaceships yet to appear from soup, alongside crab and 25P3H1V0.1.
Glider synthesis
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] A 24-glider synthesis was found by iNoMed on July 6, 2021.[4] The synthesis was reduced to 23 gliders on April 14, 2023, when the cost of the base 14-cell still life[5] was reduced from 6 to 5 gliders.[6] The synthesis was reduced to 22 gliders on November 25, 2023.[7]
