Copperhead.png

Copperhead is a c/10 orthogonal spaceship discovered by zdr on March 5, 2016. The ship hauls a block behind it, which makes for interesting reactions involving other ships.

Simon Ekström found what appeared to be a tagalong with a large spark on March 20, 2016. However, the apparent tagalong actually temporarily interacts with the hauled block. The combined pattern is therefore generally considered to be a distinct spaceship, named fireship due to its unusual spark.

Did you know...

  • ... that no way is known for a 3×3 pattern to be tiled into an M×N rectangle to produce a Garden of Eden, but that there are 4×3, 4×4 and larger tiles that can be repeated in this way to produce GoEs?
  • ... that there are spaceship stabilizations of agars?
  • ... that block is the only known finite strict still life where each living cell has exactly 3 neighbours?
  • ... that all strict still lifes up to and including 14 cells have been found by apgsearch in asymmetrical 16×16 soups?
  • ... that c/2 orthogonal and c/4 diagonal were the only speeds of spaceships seen to emerge from asymmetric soups on Catagolue until 2020, when a loafer appeared naturally?
  • ... that all currently known standard Herschel conduits produce the same Herschel great-grandfather pattern, except for Fx158?
  • ... that eater 1 is the smallest asymmetric still life?
  • ... that in Life, no spaceship can exist with a speed of (m,n)c/x where (m+n)/x > 0.5?
  • ... that even without using fixed-cost reverse caber tosser technology, an N-bit strict still life – specifically, some length of long long (...) boat or shipcan be constructed for any odd integer N using no more than 20 gliders, and for any even integer N using no more than 21 gliders, using a temporary tubstretcher?
  • ... that even without using fixed-cost reverse caber tosser technology, some specific N-bit period-2 oscillators can be constructed for any even integer N using no more than 27 gliders, and for any odd integer N using no more than 29 gliders, using a temporary tubstretcher?
