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]
