What is this? A puzzle cache that tells you how to solve it! That has to be a doddle, or is it? I'll leave that for you to decide. All you need to do is add up a few (well actually quite a lot of) numbers.
Add up all of the prime numbers from the 1st, which is 2 up to and including the 7814731st which is 138173383. That is it! Sorry there is no story as in the Henry caches, but I thought the puzzle was hard enough without the need to confuse anybody attempting it!
When you have an answer put it in the checker and if correct you will be supplied an adjustment that needs to be made to the geochecker coordinates as the cache couldn't be placed at that location. I could have put the adjustment in this description, but decided that if I had to move the cache, it would be easier for me to adjust and easier for anybody who had solved but not found the puzzle, if the offset information was put in the geochecker. I would recommend that once you have a correct on the checker, you save the geochecker coordinates in the cache notes so that you can revisit the checker if required.
There is also a hint, parking details and other information in the geochecker.
The difficulty is based on the puzzle and not the cache itself.
Enjoy!
