1xnquadraticgrowth.png

1×N quadratic growth is a pattern found by Stephen Silver on April 20 2011; it is the first pattern discovered that starts out with the thickness of a single cell and has quadratic growth. It uses the breeder from Nick Gotts' 26-cell quadratic growth.

On November 6, 2014, Chris Cain completed a 14812×1 pattern that exhibits quadratic growth — and on November 10th he reduced this to 7242×1.

Did you know...

  • ... that the first self-constructing Conway's Life pattern was built in 2010?
  • ... that the first glider synthesis for a c/3 spaceship was completed in 2014?
  • ... that the first "macro-spaceship" gun (a Gemini spaceship gun) was constructed in 2010, followed by the HBK gun in January 2015 and a Demonoid gun in December 2015?
  • ... that the waterbear was the first known high-speed oblique spaceship, many orders of magnitude faster than Gemini spaceships and half-baked knightships?
  • ... that there are no known direct reflectors for lightspeed wire signals, or for signals in 2c/3 wires, but that very large reflectors for these signals can be constructed using stable or periodic circuitry?
  • ... that 24 ten-cell patterns exhibit infinite growth, with 17 unique pattern types, but that it has been proven that no nine-cell pattern exhibits infinite growth?
  • ... that all still lifes up to 18 bits have a known glider synthesis, but it is still not known whether all still lifes are synthesizable?
  • ... that the French kiss remained without a glider synthesis until 2013?
  • ... that Adam P. Goucher's distributed Catagolue soup-search project, started in February 2015, has already tested more random soups than any previous such project, and has contributed to the reduction of many glider construction recipes?
  • ... that with the appearance of the 0E0P metacell, the number of periods for which strict volatility 1 oscillators were known went from 12 to infinity?
