This week's featured article

A switch engine is a methuselah that was found by Charles Corderman in 1971. It is unstable by itself, but it can be used to make c/12 diagonal puffers and spaceships. There are two basic types of stabilized switch engine, both of which were also found by Charles Corderman: the period 288 block-laying switch engine (the more common of the two) and period 384 glider-producing switch engine. These two puffers are the most natural infinite growth patterns in Life, being the only ones ever seen to occur from non-symmetric random starting patterns.

Pattern collection

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

  • ... that glider constructions for the B29, X66, half-X66 with HWSS, Pushalong 1, 25P3H1V0.2, 30P5H2V0, 30P4H2V0.4, a pufferfish spaceship, and the weekender were discovered in 2015 -- after fifteen years of intermittent efforts in the case of the weekender?
  • ... that since 2014, more new spaceship syntheses have been completed than were found in all the years between 1970 and 2013?
  • ... that as of 26 July 2015 there are 161 different still lifes known to be constructible by colliding four gliders, but it is not known if the list is complete?
  • ... that in 2014 a new natural infinite growth pattern was discovered, starting from a symmetric random starting configuration?
  • ... 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?
  • ... that the waterbear is the single 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?
  • ... 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?
