This week's featured article

Eater1.png
Eater 1 (or fishhook or simply eater) was the first discovered eater. Its ability to eat various objects was discovered by Bill Gosper in 1971. It is the smallest still life that is neither radially symmetric nor symmetric through a line, and it is the thirteenth most common still life, being less common than mango but more common than long barge. It only takes four generations to recover from being hit by a glider, making it the fastest-recovering glider eater, and it is also the smallest glider eater. As such, it appears as a stabilizer at the corner of dozens of oscillators including 36P22, buckaroo, P54 shuttle, pentoad, pre-pulsar shuttle 47, and snacker.

Pattern collection

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

Did you know...

  • ... that no pattern inside a 6×6 bounding box is a Garden of Eden?
  • ... that Garden of Eden patterns with only 45 ON cells have been found?
  • ... that it is known that no Garden of Eden patterns exist that are 1, 2, or 3 cells high, but that it is currently an open question whether a 4-cell-high GoE can be constructed?
  • ... that 6-cell-high Garden of Eden patterns were constructed as far back as 1973, but 5-cell-high GoEs were unknown until Steven Eker found some in 2016?
  • ... that in 2016, patterns were found that have great-great-grandparents but no great-great-great-grandparents?
  • ... that no way is known for a 3×3 pattern to be tiled into an M×N rectangle to produce a Garden of Eden, but that there are 4×3, 4×4 and larger tiles that can be repeated in this way to produce GoEs?
  • ... that there are spaceship stabilizations of agars?
  • ... that block is the only known finite strict still life where each living cell has exactly 3 neighbours?
  • ... that all strict still lifes up to and including 14 cells have been found by apgsearch in asymmetrical 16×16 soups?
  • ... that c/2 orthogonal and c/4 diagonal were the only speeds of spaceships seen to emerge from asymmetric soups on Catagolue until 2020, when a loafer appeared naturally?
