This week's featured article

Tanner's p46 is a period 46 oscillator that was found by Tanner Jacobi in 2017 involving a pi running a small conduit. Mark Niemiec posted a 19-glider synthesis two hours after its discovery. Various guns can be constructed by combining two of the oscillators themselves, one of which produces middleweight spaceships without any gliders required.

Did you know...

  • ...that all strict still lifes up to and including 13 cells, and all but one with 14 cells, have been found via soup searching using apgsearch?
  • ...that c/2 orthogonal and c/4 diagonal are the only speeds of spaceships seen to emerge from asymmetric soups on Catagolue?
  • ...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 an N-bit strict still life – specifically, some length of long long (...) boat or barge – can be constructed for any odd integer N using no more than 39 gliders, and for any even integer N using no more than 38 gliders, using a temporary tubstretcher?
  • ... that an N-bit period-2 oscillator can be constructed for any odd integer N using no more than 45 gliders, and for any even integer N using no more than 46 gliders, using a temporary tubstretcher?
  • ...that it is currently an open question as to if there exists a periodic pattern whose only predecessors are its own evolutionary sequence?
  • ...that it can be proved reflectorless rotating oscillators exist in Life, although none have yet been found or constructed?
  • ...that there are currently known elementary spaceships with speeds c/7 and c/10 orthogonal, but none with c/8 or c/9?
