A chess king starts at a position A in the top row of a standard chessboard. The number of paths of length 7 to a
position B in the bottom row is a perfect square, but not a perfect cube.
The number of paths of length 7 from A
to a position C in the bottom row is a perfect cube, but not a perfect square.
The number of paths of length 7 to a
position D is both a perfect square and a perfect cube.
How many chess king paths of length
5 are there from B to C?
See my post belowbelow. There was some problem sending the post.
