The cache is NOT at the posted coordinates.

To find the cache you will need to solve this following puzzle:

The following encrypted 3x3 matrices hold the final location of the cache.

[ 0 17 21 ] [ 07 18 10 ]
[ 0 22 32 ] [ 08 27 18 ]
[ 0 26 28 ] [ 12 22 12 ]

The KEY to unlocking the required numbers lies in the following 3x3 matrix.

[ 2 1 1 ]
[ 3 2 1 ]
[ 2 1 2 ]

In order to decrypt the matrices, it is a simple matter of finding the inverse matrix (KEYi) of KEY, then multiplying KEYi by each of the encrypted matrices above.
