Zlife, or B3/S234z, is a non-totalistic cellular automaton first thoroughly described by Lucy D'Agostino on December 19, 2023. It is similar to Life but differing with a 4z survival condition, which has the effect of making soups take longer to settle down.

Still lifes

All still lifes that work in Life work in this rule due to the addition of a survival condition, though the reverse isn't true. The simplest example of this is the Z-pentomino, which dies in Life but is stable in Zlife:

x = 3, y = 3, rule = B3/S234z b2o$bo$2o! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]]

Oddly, the Z-pentomino is 18 to 19 times rarer than the boat across all soup symmetries, even C2_1, its native symmetry.

The dead spark coil is much more common in Zlife due to the pi-heptomino evolving into one, plus a beehive. Hats are more common as well.

Spaceships

All of the 4 most common spaceships from Life (glider, LWSS, MWSS, HWSS) work in Zlife. In addition, there is an 8c/16 spaceship native to the rule.

x = 56, y = 12, rule = B3/S234z 53bo$52b3o$38b3o10b2o2bo$25b3o9bo2bo12b3o$12b3o9bo2bo12bo12b2o$2o9bo2b o12bo8bo3bo$obo11bo8bo3bo8bo3bo10bo2bo$o13bo12bo12bo10b2ob2o$11bobo10b obo10bobo15bo$51b2ob2o$51bo$52bo! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]] #C [[ THUMBSIZE 2 ]]

Known speeds are c/2o, 2c/5o (44P5H2V0) c/3o, 2c/7o (Weekender), c/4o[1], c/5o (Snail), c/10o (Copperhead), c/4d and c/5d (58P5H1V1)

Puffers

Some puffers are known to exist in Zlife, like Puffer 2 a naturally-occuring p60 blinker puffer, as well as some high-period c/2o puffers.[2]

Oscillators

Most small oscillators from Life work in Zlife, though higher-population and higher-period ones are less likely to work. Some oscillators native to Zlife are known, such as this p58 statorless century hassler:

x = 12, y = 5, rule = B3/S234z 2o$obo6bo$b2o6b2o$2bo6bobo$10b2o! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]] #C [[ AUTOSTART ZOOM 12 GPS 20 ]]

The existance of oscillators of periods 64+ has been proven using Snark64 loops, but the question of if Zlife is omniperiodic remains unanswered.

Guns

The Gosper glider gun and the p4-assisted period-28 glider gun both work in this rule.
