29P3H1V0 is a small c/3 orthogonal spaceship discovered no later than October 21, 2005.[1]
This spaceship is the fourth-smallest known c/3 orthogonal spaceship (after 25P3H1V0.1, 25P3H1V0.2 and Edge-repair spaceship 1).
This was formerly the smallest spaceship with no known glider synthesis. On June 29, 2022, Goldtiger997 completed a synthesis using 35 gliders.[2] It is currently the second smallest spaceship after wings with a glider cost exceeding its minimum population when not counting reverse caber-tosser technology.
