|Parallel half-baked knightship or Parallel HBK is a knightship based on the well-known half-bakery reaction with a glider, and an improvement over the original half-baked knightship. There are several significant differences in design between the original half-baked knightship and Chris Cain's smaller version. The slow-salvo constructions are done serially in Goucher's design, and an extra glider is used to suppress the salvo that triggers the half-bakery trails.
On January 3, 2015 Chris Cain built a HBK gun, that can run in Golly in reasonable time.
The gun's design implies an easy synthesis with 57,286 gliders, though this is considerably larger than an earlier 38,380-glider synthesis by Michael Simkin.
In the news
|The LifeWiki contains one of the most comprehensive catalogues of patterns available on the internet. Within it you will find:
Did you know...
- ... that after ten years with no new small spaceship syntheses, a glider construction was found for the c/7 loafer in 2013 less than three hours after its discovery?
- ... that glider constructions for three previously inconstructible spaceships (the dart, the crab, and the Parallel HBK) were discovered in 2014?
- ... that glider constructions for the B29, X66, half-X66 with HWSS, Pushalong 1, 25P3H1V0.1, 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 19 July 2020 there are 232 different still lifes known to be constructible by colliding four gliders, but it is likely that this list is not 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 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?
