This grid of 13 x 13 represents latitude and longitude coordinates of a Geocache in the form 54 XX.XXX 5 XX.XXX i.e degrees followed by minutes and decimals of a minute to three places - 13 digits in all. We know that the latitude (the first part) starts with 54 and we know the longitude starts with 5. The cache name is Obfuscate.

I initially thought that this is probably a simple extract the numbers and ignore the rest as the first two columns add to 5 and 4 which is what was expected. But the third column adds to 7 and should only be a max of 5 (Minutes). Then I thought ROT47 translation as there are all those brackets etc but no go.

Any thoughts about how to solve?
