      The surface of the unit sphere in 3D is defined by
      <pre>
        x^2 + y^2 + z^2 = 1
      </pre>
    </p>

    <p>
      The integrands are all of the form
      <pre>
        f(x,y,z) = x^a y^b z^c
      </pre>
      where the exponents are nonnegative integers.
      If any exponent is an odd integer, the integral will be zero.
      Thus, the "interesting" results occur when all exponents are even.
