All nine fields of given shape are to be filled with natural numbers so that:
• each of the numbers 2, 4, 6, and 8 is used at least once,
• four of the inner square boxes containing the products of the numbers of adjacent cells of the outer square,
• in the circle is the sum of the numbers of adjacent cells of the inner square.
