Please be aware that the cache is not at the co-ordinates listed above and they are not parking co-ordinates either. The D4 level relates to the actual solving of the puzzle - the cache itself should be a lot easier to find!
For this puzzle cache all you need to do is fill the grid below with the numbers 1 to 49 - they need to connect horizontally, vertically or diagonally. The start and end numbers have been highlighted in yellow.
The formula for the co-ordinates, at which the cache is located, is as follows:
N ab c.ad W00e ab.fb
