46P4H1V0 is an unnamed c/4 orthogonal spaceship discovered by Tim Coe in May 1996.[1] It was the smallest known c/4 orthogonal spaceship until the discovery of 37P4H1V0.
It was the first c/4 orthogonal spaceship for which a complete glider synthesis was found, by Tanner Jacobi and Martin Grant on Febuary 4, 2019 with 105 gliders.[2] This was later reduced to 88 gliders with a repeat time of 572 ticks due to optimizations by various people.[3] Goldtiger997 constructed a 46P4H1V0 gun based on this synthesis on October 22.[4]
