While working in your basement, you notice there is a portion of concrete which is not like the rest. It is funny you never noticed it before, but most of the time there was a rug covering it. Tapping on the area made a somewhat hollow sound, so hammer in hand, you smash into the concrete... Hands ringing, but hole made you see an object hidden under the concrete.
Getting a bigger hammer, you open up the hole more to allow for the object to be removed, and then pull out a small, but heavy trunk. There is a lock on it with 6 digit places and what appears to be the numbers 0-9 inclusive.
Inspecting the trunk, there is writing all over it. You notice 6 distinct strings of characters, but there is no indication of the order of the strings. These must have something to do with the contents, the combo, or both!
The characters within each string can be re-arranged and arrive at the same result...
After puzzling over this trunk and strings, you look at the lock a bit closer. Hardly noticeable under the grime is the inscription $27$, and on the other side is inscribed $10$. Once you clean up the lock as best you can, you also notice a faint inscription on the lock bar... Count the strings, you'll do just fine... make your math no greater than 9. Strange indeed...
What is the combination, and what is inside? (2 answers needed)
