The cache is not at the published coordinates
To find the coordinates you will have to print out the two attached puzzle pages and then cut out all the pieces. That will give you 20 hexagons, but a truncated icosahedron has 32 sides, so you will have a lot of holes in the structure!
Tape the hexagons together at the edges with matching letters. There is just a slight problem that many of the edges are not labled!
Build your truncated icosahedron ( a 3-D figure) and the unlabled edges will all come together correctly
Read the coordinates by following the red arrow around the structure.
This should be a puzzle that anybody can do !
