This week's featured article

Rich's p16 is a period 16 oscillator that was found by Rich Holmes on July 5, 2016 using Adam P. Goucher's apgsearch. It consists of a bi-boat interacting with unnamed objects that then create two more boats in the exact same position, but flipped. Tanner Jacobi and Michael Simkin used Rich's p16 to optimize various guns, and Blinkerspawn found a glider synthesis for it, both the day of its discovery.

Did you know...

  • ... that loafer is the fifth smallest non-flotilla spaceship, but was discovered 43 years after the four spaceships smaller than it?
  • ... that despite being the fourth smallest non-flotilla orthogonal spaceship, loafer has never appeared from a single randomly generated soup?
  • ... that all known glider eaters take at least four ticks to recover to their original state after eating a glider?
  • ... that the smallest 31c/240 spaceship does not make use of the 31c/240 reaction?
  • ... that there is roughly one chance in 10^(N/3) that a still life appearing out of random soup will have a population of exactly N cells?
  • ... that the number of still lifes with N+1 bits is roughly 2.48 times larger than the number of N-bit still lifes?
  • ... that the odds of a randomly-chosen 20x20 soup pattern being a methuselah that lasts between 1000N and 1000(N+1) ticks, is roughly the same as the odds that it will last any amount of time longer than 1000x(N+1) ticks?
  • ... that all still lifes up to 16 cells can be synthesized at a cost of less than one glider per cell?
  • ... that the first elementary knightship, Sir Robin, was discovered only in 2018, with there having been a very close call in 2004?
  • ... that there is a 6x2 counterexample to the Coolout Conjecture, proving that patterns that are internally compatible with stability can not always be made part of a larger still life, no matter what cells are added around the edges?
