Title: Coordinates hidden in a matrix of numbers
Post by KBacher on Sep 3^rd, 2008, 4:37pm

I've been given a puzzle and am at my wits' end trying to solve it, and hope you can help! Hidden in the following matrix of numbers is a set of geographical coordinates, most likely in a format similar to the following:

N 46° 50.200 W 121° 42.500

Here's the matrix:

6 6 7 8 4 3 6 7 8 9 7 4 9 3 3
4 7 3 3 7 3 6 7 8 9 3 4 4 4 8
7 6 4 6 8 7 4 9 8 3 6 9 3 7 8
2 6 3 6 6 3 8 9 3 6 8 9 8 9 6
3 3 4 7 3 3 7 8 9 6 7 3 8 3 6
7 6 4 6 8 7 4 9 4 8 6 3 7 3 3

Any ideas?

There are plenty of ways to get 15 digits from a matrix with 15 columns...

I guess we'll have to find some order in the matrix.
For instance, these sequences appear 2 times:
7 6 4 6 8 7 4 9
and
3 3 4 7 3 3 7

If the number is simply found in one of the horizontal rows, then there are only a few possibilities. There is no 1 in the matrix, so it seems we're only looking for a 14 digit number. The minutes must be below 60. That would only seem to offer two possibilities.

N73 37.367 W89 34.448
N76 46.874 W98 36.937

Of course, if the number could be 14 digits, it could also be 13, or 12. That opens other possible choices.

There is no 0, no 1, a single 2 and no 5.
