Only Connect #70 Mystery Cache

Number 70 of the Only Connect series of puzzle caches. The published coordinates are not those of the cache. Solve the puzzle to find them and they lead to a magnetic BYOP final. The cache itself can be found at an appropriate final location, where you will need to set your radars to stealth mode. Group discussions at GZ are not recommended, sign the log and move on.

You will find the rest of the series by clicking on this link to the Only Connect bookmark list.

Similar to OC#63, say what you see.......when you have identified A to F and how they are connected, it should be a straightforward task to identify how they are grouped.

H=the total word value of the name associated with A (2 words, A=1 ... Z=26).

I=the total word value of the name .... B (3 words).

J=the total word value of the name .... C (3 words).

K=the total word value of the name .... D (2 words).

L=the total word value of the name .... E (2 words).

M=the total word value of the name .... F (2 words).

N=the total word value of that which groups them (2 words).

The cache can be found at : N55 00.Y W001 37.Z

Where Y = I + (M + K - H) / (N - J) and Z = M * (I - N) + L + H - J
