SUMMARY
An umbilic point on an ellipsoid is defined as a location where the directional curvature is uniform in all directions. The discussion confirms that an ellipsoid has exactly four umbilic points, contrary to the assumption of potentially six. These points are critical in understanding the geometric properties of the ellipsoid and its connection to lines of curvature. The identification of these points is essential for applications in differential geometry and surface analysis.
