58P5H1V1 is an unnamed c/5 diagonal spaceship discovered by Matthias Merzenich on September 5, 2010. In terms of its minimum population of 58 cells it is the smallest known c/5 diagonal spaceship. It provides sparks at its trailing edge which can perturb gliders, and this property was used to create the first c/5 diagonal puffers. These sparks also allow the attachment of tagalongs which was used to create the first c/5 diagonal wickstretcher in January 2011.[1] A period-1540 glide-symmetric three-ship puffer was discovered by Peter Naszvadi in March 2020.[2]
The final step for a glider synthesis of this spaceship was found by Goldtiger997 and Tanner Jacobi on April 2, 2020.[3] Goldtiger997 posted a complete 220-glider synthesis, including the base still life, on the next day,[4] making 58P5H1V1 the first spaceship of its speed to be synthesized. Reductions to the synthesis have since been made.[5][6][7][8] A 58P5H1V1 gun with period 2760 was posted by Entity Valkyrie on May 22.[9]
Goldtiger997 constructed a 1G seed for 58P5H1V1 on July 7, 2020.[10] A version of this seed constellation was soon proven to be glider-constructible, opening up the possibility of self-constructing spaceships with diagonal speeds approaching c/5, where the previous limit had been c/12 with the use of constructible Corderships.
