Subject: [seqfan] Parking lot for bad drivers

Hello seqfans,

Here's a puzzle from p. 39 of "Let's be Less Stupid" by Patricia Marx:

At the parking lot for bad drivers, you are not allowed to park in a spot that is next to two occupied spots. In other words, no three cars can be contiguous--vertically, horizontally, or diagonally. ... How many cars can the lot fit.

As an example, the book shows an 8x8 "parking lot" (looks like a
chessboard) and gives a solution fitting 16 cars into this lot.

Is this in the OEIS?
