77P6H1V1 is a c/6 diagonal spaceship discovered by Josh Ball on March 25, 2011,[1] being the only known spaceship of this speed not based on seal at its time of discovery. In terms of its 77 cells it is the smallest known c/6 diagonal spaceship; however, seal has a smaller bounding box. On April 22, 2020, praosylen found a pushalong for this spaceship, shown below.[2]

On January 26, 2024, Goldtiger997 posted the final step for a glider synthesis of this spaceship.[3] Two days later,[4] this post was edited to include a complete synthesis with 259 gliders. On June 20, 2024, Entity Valkyrie used this synthesis to construct the first gun for a c/6 diagonal spaceship.[5]
