At the given coordinates you will find some green fencing.
This is constructed from several types of pieces.
Each type of piece has a number of the format "ABC D48" where ABC is a three digit number.
There are fives types of joints that I refer to as:
- L, numbered L1 L2 L3
- T,numbered T1 T2 T3
- #, numbered #1 #2 #3
- Pivot, numbered P1 P2 P3
- Base, numbered B1 B2 B3
The cache is hidden at:
N 51 (#1 + #2) (L1 + L2 + L3) . T2 B3 L3
E 000 (#2) (B3 +P1) . (P3 - T3) (B1 + L3) (#3 - T3)
