CCC 4 = croquetmike's Christmas cache No.4. No further significance! This is the only one for 2010, and is a bit of a Christmas present. There are numbered certificates for the first 10 finders and unnumbered ones for later finders. Let's see if those first 10 can have gone by Twelfth Night.
A bit of detective work may be needed to assign numbers to the following caches.
A: GC18C7K
B: GC4TYBC
C: GC1HFRV
D: GCNJFX
E: GC24ZB8
F: GC1ZHFB
The cache is at:
N 51 12 . (D * D) * (B + F) - (B * E)
W 000 32 . C * (D * D) - (A * D) + (B + F)
