Geocache Description:

The cache is NOT located at the posted coordinates.

Note: For the purpose of this puzzle, let's only deal with 2D bricks instead of 3D.

I have with me 15 bricks of size 2x1 square unit. I've always wanted to use all of them to build a rectangular brick wall, 3-unit story high and 10-unit wide.. I'm now curious on how many different arrangements we can do this. Please help me find this number and I'll reward you with a cache ...

For your information, I've attempted to fill only up to 3x4 and I know there are 11 different ways to do this ... I hope this helps.

Call the number of different arrangements to do this X. Divide X by 1000 and then:
- subtract it from the posted North coordinates, and
- add it to the posted West coordinates.

FTF Prize: A $1 gold coin

Checksum of X is 13.

Kudos goes to 40, who killed the puzzle and nabbed the FTF. Congrats to Roktman as well for a very careful calculations of the different arrangements.
