Clouds 2

From Softology's collection · B13-14/S12-26

Clouds 1 with fewer births: thinner, lumpier clouds.

Clouds 2 in the 3D Game of Life: cells as cubes in a 15×15×15 box, 40 generations in.
After 40 generations from a random fill with 60% of cells alive, in a 15×15×15 box that wraps at its edges: 2,414 live cells.

How the rule works

Picking it in the app restarts the world from a random fill with 60% of cells alive. Its seed is fixed, so it is the same world every time, one still alive 40 generations later in the default 15×15×15 box; N tries another seed.

B lists the neighbour counts at which an empty cell is born, S those at which a live cell survives, and C the number of states. How to read a rule
