## Geocache Description:

One of a series of easy to find (the puzzle ones may not be easy to solve) caches. This one is a Puzzle.

I was rereading one of my old A-level maths books the other day (honestly!). In the last chapter on "puzzles" they posed the following:

"Fill a 3 * 3 grid with digits 1 to 9 so that each 3 digit row number and each 3 digit column number are exactly divisible by 11."

The one I want has the total of the 3 rows and the 3 columns being maximal, and with the rows total greater than the cols total.

The end result will be

A B C

D E F

G H I

The cache may be found at N 51 9.CGG, W 0 2B.HDG

To clarify matters, this cache does NOT require entry to any private land.

Please only log a find if you have signed the log. If you haven't, try adding a "write note" instead. Thanks.
