A : 1
B : 2	C : 3	D : 4
E : 5	F : 6	G : 7
	H : 8

Arrange the numbers in the grid above in such a way that no two adjecent cells (horizontally, vertically or diagonally) have consecutive number in them. For example 1 must not be next to 2. (The letters are shown so that you can easily refer to specific individual boxes.)

(From: http://www.ocf.berkeley.edu/~wwu/riddles/intro.shtml)

Here are all possible solutions for all combinations of the numbers that satisfy the given conditions:

(A, B, C, D, E, F, G, H)

(2, 5, 8, 6, 3, 1, 4, 7)
(2, 6, 8, 5, 4, 1, 3, 7)
(7, 3, 1, 4, 5, 8, 6, 2)
(7, 4, 1, 3, 6, 8, 5, 2)
