25P3H1V0.1 is an unnamed c/3 orthogonal spaceship discovered by Dean Hickerson in August 1989,[1] being one of the first c/3 spaceships to be discovered.[2] 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. It also has edge-repair capacities.
Additional components
This spaceship is capable of pulling a 16-cell tagalong, resulting in a 41-cell spaceship.
Occurrence
- Main article: List of natural spaceships
At 25 cells, it is one of the three smallest spaceships yet to appear from soup, alongside crab and 25P3H1V0.2.
Glider synthesis
Martin Grant discovered a glider synthesis for 25P3H1V0.1 on January 6, 2015.[3] Goldtiger997 and Tanner Jacobi reduced this synthesis to 19 gliders on October 5, 2020, making 25P3H1V0.1 the second cheapest c/3 spaceship to construct, after Edge-repair spaceship 1's 17.[4][5]
