  3. Radius of circles = sqrt(SW-sqrt(3)*S)/2
    With P=X(17): A'B'C' is the 2nd half-diamonds triangles
    With P=X(18): A'B'C' is the 1st half-diamonds triangles

    Explanation: Find three points A', B', C' such that AB'C', BC'A' and CA'B' are equilateral. The problem has two solutions and the triangles A'B'C' and A"B"C" (2nd solution) are the 1st and 2nd half-diamond triangles.
