Cell Entry Expansion (Posted on 2015-05-30)

Each of the 25 cells in a 5x5 board is zero. Consider any arbitrary cell and increase by 1 the number in this cell and all cells having a common side with it.

Is it possible to obtain the number 2012 in all cells simultaneously?
If so, give an example.
If not, prove it.

No. It is not possible for N=2012.
For an explanation, refer to the solution submitted by Steve Herman in this location.
