Still lifes

Anyone know if there are still lifes in Bugs other than the domino and duoplet? Gzaytman (talk) 14:42, 22 November 2022 (UTC)

For a hypothetical still life pattern consider a live cell touching the edge of the bounding box: if it survives then it must follow S1, because S5-i678 would put other live cell(s) beyond bounding box, and S5i would allow for B3i birth outside of the bounding box. And then S1c corresponds to duoplet and S1e domino. Hence no other still life is possible. GUYTU6J (talk) 16:43, 22 November 2022 (UTC)

That proves too much. For example, if I remove B3q, I can construct the following still-life.

x = 13, y = 13, rule = B3-q567/S15678 6bo$bo4bo4bo$2bobo3bobo$5b3o$2bob5obo$3b7o$2ob7ob2o$3b7o$2bob5obo$5b3o $2bobo3bobo$bo4bo4bo$6bo! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]]

If I remove B5, I can also construct a still-life.

x = 12, y = 12, rule = B367/S15678 o4b2o4bo$bobo4bobo$4b4o$bob6obo$2b8o$ob8obo$ob8obo$2b8o$bob6obo$4b4o$b obo4bobo$o4b2o4bo! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]]
