|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 several different universal constructors in Conway’s Life have been shown to be capable of constructing their own circuitry?
- ... 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 twin primes or Fermat primes?
- ... that two completely different types of oblique spaceships, the waterbear and the half-baked knightship, were constructed in 2014?
- ... that no Caterpillar-type spaceships were completed for almost ten years after the original Caterpillar was constructed in 2004, but that two different designs, the waterbear and the centipede, were finished in 2014?
- ... that the first spiral-growth pattern in Conway's Life was constructed in 2014?
- ... that among known glider recipes for irreducible objects, the Gemini spaceship has the largest known minimal recipe, currently 173,449 gliders — the runner-up being the Parallel HBK with a 38,380-glider synthesis?
