    I am looking for max. total distances of 4 points, i.e. sum distance (between: 1&2 + 2&3 + 3&4 + 2&4 + 1&3 + 1&4)
    if they are on the surface of the sphere.. Are they going to form a regular tetrahedron?
    thank you.

    if they are the maximum distance away from each other then yes they will form a regular tetrahedron. Your triangles will be equilateral. If you take the curve into account no. if one point is a few mm short no
