Geocache Description:

The cache is NOT at the posted coordinates. You have to solve the puzzle below to get the final coordinates.

This puzzle may be a 5-star difficulty for some and for others it may be a 2-star difficulty so I've rated it right in the middle. All 15 numbers are in the puzzle and they're in order from A to F.


A = the last Roman numeral when written lexicographically.
B = the largest known number whose square and 4th power use different digits.
C = the smallest possible magic constant of a 3×3 magic square of distinct primes.
D = the number of trees with 10 vertices. (multiply by 2)
E = the smallest number of distinct squares needed to tile a square.
F = the maximum number of spheres that can touch another sphere in a lattice packing in 6 dimensions. (divide by 6)

You can validate your puzzle solution with certitude.
