25P3H1V0.1 is an unnamed c/3 orthogonal spaceship discovered by Dean Hickerson in August 1989 and was the first c/3 spaceship to be discovered.^{[1]} In terms of its 25 cells, it is tied with 25P3H1V0.2 as the smallest c/3 spaceship, although unlike that ship, it has a population of 25 in all of its phases, as well as a smaller bounding box.
Martin Grant discovered a glider synthesis for 25P3H1V0.1 on January 6, 2015.^{[2]}
