This week's featured article

The R-pentomino is a methuselah that was found by John Conway in 1970. It is by far the most active polyomino with fewer than six cells; all of the others stabilize in at most 10 generations, but the R-pentomino does not do so until generation 1103, by which time it has a population of 116. It releases a glider in generation 69, which was noticed by Richard K. Guy and was the first glider ever observed. The stable pattern that results from the R-pentomino consists of eight blocks, six gliders, four beehives, four blinkers, one boat, one loaf, and one ship.

Pattern collection

The LifeWiki contains one of the most comprehensive catalogues of patterns available on the internet. Within it you will find:

Did you know...

  • ... that the smallest known sawtooth pattern in Conway's Life consists of only 177 ON cells?
  • ... that there are now over a hundred and twenty known Herschel conduits, counting stable conduits only, and a much larger number if oscillator-supported conduits are included?
  • ... that Demonoids, caterloopillars, orthogonoids and half-bakery knightships are the only known types of spaceships with fixed slope but adjustable speed?
  • ... that a pattern exists in which no cell in the unbounded Life plane ever becomes periodic?
  • ... that several candidate universal constructors have been demonstrated in Conway’s Life, but as of June 2015 none have been formally proven to be universal?
  • ... that there are dozens of known Cordership variants, including puffers, rakes and wickstretchers, with periods of any multiple of 96?
  • ... that greyships have been constructed with speeds of c/2, c/3, c/4, c/5 and 2c/5?
  • ... that most greyships travel parallel to the stripes in their included agars, but a few travel perpendicular to the stripes, or "against the grain"?
  • ... that a pattern has been constructed that calculates and prints out the digits of pi in decimal, and a similar one prints out the decimal digits of the Golden Ratio?
  • ... that several different patterns have been constructed to calculate and display the sequence of prime numbers, and some have been adapted to display only prime pairs or Fermat primes?
