Puzzle 3 -- Determine the Target

Puzzle: The link to Mr. Chase's website redirects to a document containing the next puzzle:

Detective Holmes, we’ve found a message that needs to be deciphered. This will determine who your next target is. You'll need to get to the bottom of things, but first, how about a quick read of the top?

[Solution: Teams realize that the symbols within the cells of the table are dancing men from Sherlock Holmes, and top row of the tables, once alphanumericized, spell out “determinant use.” This indicates that the determinant of each of the 2x2 matrices must be taken, which provides the numbers 2576 on top and 12 38 9 on the bottom, leading teams to locker 2576 with combo 12 38 9.]

• Hint 1: Sherlock would be an expert at recognizing these dancing men.

• Hint 2: These dancing men seem to be organized into 2x2 squares…

• Hint 3: Maybe the tops of each row aren’t only numbers after all… What’ll unlock the answer to this puzzle?
