Knights Puzzle (Bathroom)

Hint 1 of 10:

There aren't too many strategies to this puzzle, other than to make
educated guesses.

Hint 2 of 10:

For one, you should try to finish the far left and right sides of the board
first.  The corners are especially good starting points.

Hint 3 of 10:

Then you want to think a few moves ahead.  Try to make moves that let you
keep white pieces on the left and black pieces on the right, and look for
moves that let you move the location of the empty square without disturbing
too much else.

Hint 4 of 10:

Coming is one solution (probably not the most efficient) to the puzzle.  I
use standard notation for this UHS file to describe the piece to be moved.
