Still lifes

I'll run the still life counts when I get to my real computer tomorrow and update that section accordingly. Nathaniel 15:11, 14 June 2009 (UTC)

Did anything ever become of this? Sounds interesting. --Tropylium 08:08, 18 February 2012 (CST)

Small seeds

Seed patterns of radius up to ten typically evolve into a still life.

(Emphasis mine.) Doesn't really look like they do. Sure, straight lines up to 10 all stabilize, but looking at eg. polyominos in the L, F and S series, almost everything from 5 on explodes chaotically (with the exception of the F-hexomino and S-pentomino). A few dozen 5×5 soups I tested all exploded as well.

More symmetric seeds seem to have better odds of stabilizing tho — the Z-pentomino is stable, the Z-heptomino and 10 thru 12-minos become still lifes, and the Z-hexomino becomes two ladders; the smallest 3×n rectangle that explodes is n=15, tho quite a few sprout a few ladders. --Tropylium 08:05, 18 February 2012 (CST)

Islands of stability

I noticed islands of stability in straight lines. 1-10 stabilize. 11 and 12 explode. 13 and 14 explode for a while, and then stabilize into ladders. 15 and 16 quickly stabilize into ladders. 17 and 18 stabilize very quickly. 19 and 20 quickly stabilize into ladders. 21 and 22 explode. 23 and 24 also stabilize quickly. 25-28 explode. 29 and 30 also stabilize quickly. 31 and 32 explode. -wwei23 2:47PM 10/17/2015 NY time


I heard that LwoD is an EXPANDING universe(sorry about the capitals), not an exploding one.-wwei23

The distinction doesn't appear to be very firmly defined in the first place. --Tropylium (talk) 20:31, 14 November 2015 (UTC)
