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.

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

RLE: here
gollark: Hmm, it's down to 298MB somehow.
gollark: I have my data package somewhere, so just filter to public chat or something, and bees are your apiforms!
gollark: A gollarious neural network *would* have many practical applications.
gollark: I was telling lyricly to do so.
gollark: Look, if you want, you can send me your entire discord data package and I can train GPT-2 on you.
