Apropos of nothing - when you have a Cartesian coordinate or square, what's the term for the 8 points immediately around it? as in up down left right and diagonals? Could've sworn there's a special name for it

perhaps "neighborhood"? Not sure that is a precise technical term for it.

Aha, got it - the https://en.wikipedia.org/wiki/Moore_neighborhood Thanks Andy, that was enough for Google to get me the rest of the way.
