56P6H1V0 is a spaceship discovered by Hartmut Holzwart in April 2009^{[1]} that travels at a speed of c/6 orthogonally. With 56 cells it is currently the smallest known orthogonal c/6 spaceship, surpassing dragon with 102 cells.
The final step for a glider synthesis of this spaceship was found by Goldtiger997, Tanner Jacobi, AforAmpere, and Aidan F. Pierce on March 22, 2020.^{[2]} A complete synthesis was posted by Martin Grant on March 25, making 56P6H1V0 the first c/6 orthogonal spaceship, and the first period6 spaceship, to be synthesized.^{[3]} Improvements to the synthesis have since been posted.^{[4]}^{[5]} A gun for this spaceship was completed on December 1,^{[6]}^{[7]} and a slightly smaller version was posted on December 8.^{[8]}
