I just found the RSA page with their 12 challenges. I see that it is going
to be really hard...

It's for a new card game that consists of a series of puzzles. This is
ranked as one of the absolute hardest ones - All it says is "The Thirteenth
Labour" as a title, "64/12/8" under that and then 176 two-figure hex values.
A line of 5 cows are at the bottom. People are hinting that this is in
reference to the group that broke one of the 12 challenges. There is
absolutely no other information...

Thanks anyway
