The published co-ordinates are not for the location of the cache. Instead, if …
K I K I = L M N P
J A C K = Q R S T
… then the cache can be found at the following coordinates …
N 51 20.(P-Q)(Q-S)(M-L) W 000 44.(R-N)(T-R)(T-L)
Please don't leave any additional clues (subtle or otherwise) in your log.
And please could you bring something to write with, as there is no pen/pencil in the cache.
You can check your answers for this puzzle on Geochecker.com.
(Depending on the source, there appears to be two difference values for R and so while there is this difference, please choose the lower value).
