Note: The posted co-ordinates are bogus.
However, GZ is within 2 km. of them.
The following diagram shows a grid of 10 x 10 numbers. (You can download this as an Excel Spreadsheet here if you wish).
To calculate GZ, you need to work out the largest combination of 10 cells, one from each row and column. i.e. Select a cell, then remove all others in that row and column. Repeat until you have chosen 10 cells. Add these 10 numbers together. Repeat as often as necessary to ensure that you have the optimal choice giving you the highest possible total.
To determine the location of GZ, use your optimal solution.
- Add up the chosen cells from the first 5 Rows - this sum equals AAA
- Add up the chosen cells from the last 5 Rows - this sum equals BBB
The cache is placed at S 37° 56.AAA E 145° 16.BBB. It is a 1 litre sistema box with small swaps.
It should be an easy walk, but might be long for some.
