60P5H2V0 is an unnamed orthogonal period 5 2c/5 spaceship[1] that was found by Tim Coe in May 1996.[2]
Synthesis and destruction
60P5H2V0 is most well-known for being the first orthogonal spaceship that travels at a speed other than c/2 to be successfully constructed via glider synthesis (using 63 gliders). The glider synthesis was mostly due to Noam Elkies, with help from Mark Niemiec and Jason Summers, in March 2003.[2] Thanks to its glider synthesis, two guns have been independently constructed that create it: a period 416 gun and a period 690 gun. The synthesis has since been reduced significantly by Tanner Jacobi in December 2019[3] and Goldtiger997 in October 2020.[4][5]
It can easily be destroyed by two eater 2s as shown below.
A similar spaceship, 57P5H2V0, was synthesized in late 2020, primarily due to efforts by Goldtiger997.[6] The final step of this synthesis was previously completed on October 27,[7] while the base still life was completed on November 2.[8]
