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. Thanks to its glider synthesis, two guns have been independently constructed that create it: a period 416 gun and a period 690 gun.

It can easily be destroyed by two eater 2s as shown below.
