You are going to place all numbers from 1 to 16 on a 4×4 chessboard such that all consecutive number pairs (1-2, 2-3, …, 15-16) will be on the neighboring cells (left-right-top-down).
In how many different ways can this be done?
If the question was asked for a 2×2 chessboard, the answer would be 8.
