Geocache Description:

The cache is not at the posted coordinates.

Start by solving these snack-sized 4 by 4 sudoku-like puzzles; solutions must have no duplicate numbers within rows, columns, or diagonals. Once solved, identify the one solution within each of the 5 rows that is different from the others in that same row. Concatenate the 4 numbers from the top row of those five different puzzle solutions to form a 20-digit key. Use the key with the most widely-used stream cipher to decipher the following.

There are 48 total solutions that exist for these 4 by 4 puzzles. Within the set of 48 solutions there are only 6 unique sets or families of related solutions. Within a given family, the same solution can be represented in 8 different ways by rotation about the perpendicular and in-plan axes. The following figure illustrates how a single unique solution can be represented 8 different ways.
