Hello ...gosi?; The article "Life: nasty, Brutish and Short" by(?) Eugene McDonnell, in an old Quote Quad, I think, gives many one-liners as well. IIRC, it uses the Sharp APL cut operator, which is very similar to the ;. conjunction in J. This separates out the 3 3 subarrays, and you can just apply the life/death verb to each subarray.
